JOURNAL FREE ACCESSSteric conversion of N-benzoyl-DL-erythro-β-[2-(5-nitro)-furyl]-serine ethyl ester m.p. 117°, to O-benzoyl-DL-threo-[2-(5-nitro)-furyl]-serine ethyl ester hydrochloride, m.p. 175° (decomp.), was effected by the application of thionyl chloride, intermediately forming an oxazoline ring and with migration of the benzoyl group from nitrogen to oxygen. The latter compound was used for the attempt in obtaining threo-type N-acyl derivatives by the application of p-nitrobenzoyl, 2, 4-dichlorobenzoyl, furoyl, 5-nitrofuroyl, furylacryloyl, and 2-(5-nitro)-furylacryloyl chlorides to the O-benzoyl compound. Since the crystallization of their products was difficult, they were submitted to chromatography through alumina by which the objective compounds could not be obtained and ethyl N-acylamido-β-[2-(5-nitro)-furyl]-acrylates were obtained by the concurrent liberation of benzoic acid. On the other hand, the same reactions with benzoyl, p-chlorobenzoyl, and cinnamoyl chlorides yielded the corresponding O-benzoyl-N-acyl-DL-threo-β-[2-(5-nitro)-furyl]-serine ethyl esters in crystalline form. In the case of 2, 4-dichlorobenzoyl chloride, the final product was isolated as O-benzoyl-N-2, 4-dichorobenzoyl-DL-threo-β-[2-(5-nitro)-furyl]-serine ethyl ester. Chromatography through alumina of N-2, 4-dichlorobenzoyl-DL-erythro-β-[2-(5-nitro)-furyl]-serine ethyl ester and O-benzoyl-N-2, 4-dichlorobenzoyl-DL-threo-β-[2-(5-nitro)-furyl]-serine ethyl ester separately yielded identical ethyl N-2, 4-dichlorobenzoyl-β-[2-(5-nitro)-furyl]-acrylate, m.p. 229°, confirmed by ultraviolet absorption spectrum. A large difference in the absorption in the infrared region above 10μ was observed between the erythro- and threo-type compounds.View full abstractDownload PDF (882K) -
Studies on the Structure of N-Substituted Dithiourethanes. (3)Hiroshi Hirano1955 Volume 75 Issue 3 Pages 244-248
Published: March 25, 1955
Released on J-STAGE: February 19, 2010
JOURNAL FREE ACCESSThe substance obtained from a primary amine, carbon disulfide, and α-haloketone, heretofore assumed to be a dithiourethane compound, fails to show the absorption band in the region of 5.85μ, attributed to the C=O group, in the infrared absorption spectrum. Examination for such a cause revealed that the absorption for C=O group did not appear in compounds (I) and (II), as well as (III) and (IV), while the band appeared in compounds (V), (VI), and (VII), obtained from a secondary amine and α-haloketone, as well as in (VIII) prepared from a primary amine and β-haloketone. These results have shown that there is no ground for earlier assumptions that the disappearance of the carbonyl band was due to either the existence of the compounds in an enolized form or the overlapping of the carbonyl band with that of the C=N bond in the pyrimidine portion. It was therefore assumed that these compounds did not possess the structure of dithiourethane but were thiazolidine-thione compounds formed by its ring closure.View full abstractDownload PDF (562K) -

Studies on the Structure of N-Substituted Dithiourethanes. (5)Hiroshi Hirano1955 Volume 75 Issue 3 Pages 252-257
Published: March 25, 1955
Released on J-STAGE: February 19, 2010
JOURNAL FREE ACCESSChemical examinations were carried out on the compounds which were assumed to possess a thiazolidine-thione structure from infrared absorption spectra and fitness of this assumption was confirmed. Acid treatment of (III) and (VI), under suitable conditions respectively yielded unimolar dehydration products (IV) and (VII) and such a reactioncan easily be understood by assuming a thiazolidine-thione structures for (III) and (VI). The fact that these thiazolidine-thione compounds undergo the same decomposition reactions as the dithiourethane compounds by the action of alkali suggests that such a treatment causes cleavage between 3 and 4-positions, as in rhodanine compounds, because of the presence of a hydroxyl in the 4-position of these compounds and results in the formation of a dithiourethane compound as an intermediate.View full abstractDownload PDF (957K) -
Relationship between Chemical Constitution of Carboxylic Acids and their Nuclear Acylation of PhenolKoichi Nakazawa, Kosuke Kusuda1955 Volume 75 Issue 3 Pages 257-260
Published: March 25, 1955
Released on J-STAGE: February 19, 2010
JOURNAL FREE ACCESSNuclear acylation of phenol by carboxylic acids and formation of nuclear-substituted products by the rearrangement of phenyl esters were examined. Phenol is easily nuclear-acylated by lower fatty acids while the reaction becomes difficult with higher acids, with increase of the ester formation. Nuclear acylation with phenyl fatty acids were more difficult than the corresponding fatty acids, becoming increasingly difficult as the phenyl group approached the carboxyl group. Rearrangement of the phenyl esters showed the same trend, that of esters of lower fatty acids being facile and that of phenyl benzoate being the most difficult.View full abstractDownload PDF (677K) -
Measurement of Dielectric Constant. (2)Morizo Ishidate, Yuichi Kamura1955 Volume 75 Issue 3 Pages 260-264
Published: March 25, 1955
Released on J-STAGE: February 19, 2010
JOURNAL FREE ACCESSWhen two kinds of solvents are mixed, such as adding B to A, and the dielectric constant of the mixture is measured, an inflexion point appears in the majority of cases, the curve thereafter changing in a definite direction, and finally attaining the dielectric constant of B. By utilizing this property, some dielectric constants of solids in a liquid state were examined. A solid was dissolved in some easily soluble solvents, their concentration curves were obtained, and the line after the inflexion point was extended to meet the line of 100%, where its dielectric constant was read. When the same value is obtained with a few different solvents, this value is taken as the constant (values agreed approximately except in the case of dioxane). These experiments were carried out as the fundamental tests in high frequency analysis.View full abstractDownload PDF (640K) -

JOURNAL FREE ACCESSDehydroabietic acid was oxidized with potassium permanganate and converted to methyl 9-oxodehydroabietate when the reaction was accompanied with the formation of 1-methoxycarbonyl-1, 12-dimethyl-7-acetyl-9-oxo-1, 2, 3, 4, 9, 10, 11, 12-octahydrophenanthrene of m.p. 143-145° in 0.8% yield. The Wolff-Kishner reduction of the latter yielded 1, 12-dimethyl-7-ethyl-1, 2, 3, 4, 9, 10, 11, 12-octahydrophenanthrene-1-carboxylic acid, m.p. 142-144°. Treatment of methyl 9-oximinodehydroabietate with cold phosphorus pentachloride gave the lactam of m.p. 147-149° in 39% yield. The treatment of the same oximino compound with tosyl chloride by heating in pyridine gave the stable 9-tosyloximino compound in 92% yield which underwent smooth rearrangement to the same lactam as above on being boiled in 40% sulfuric acid. Heating of the lactam with conc. hydrochloric acid in a sealed tube resulted not only in the anticipated cleavage of the lactam ring but also the severence of the C12-C13 bond to form m-isopropylaniline and an acid of b.p3 193-195°. These results have confirmed the structure of the lactam to be as shown by (VII).View full abstractDownload PDF (743K) -

JOURNAL FREE ACCESSAromatic thiocyano compounds were prepared in order to make a comparative examination of their antibacterial, ascaricidal, and insecticidal actions, toxicity in mice, and relationship between chemical structure and biological actions. Several of the synthetic methods were examined and following procedures were adopted. Aminophenol, toluidine, anthranilic acid, and naphthylamines were substituted with a thiocyano radical according to the Kaufmann method, and further applied with phenyl isocyanate, ammonium thiocyanate, and phosgene from which phenylurea, thiourea, and phenylthiourea derivatives of these compounds were obtained. The new compounds synthesized were 2-hydroxy-4-thiocyanophenylurea, 2-hydroxy-4-thiocyanophenylthiourea, 2, 2′-dihydroxy-4, 4′-dithiocyanodiphenylurea, and 4-thiocyanonaphthyl-(1)-thiourea. Attempted substitution of thiocyano group into the ortho-position of the amino group invariably resulted in cyclization to a thiazole ring and 2-phenylureidonaphtho [2′, 1′:4, 5] thiazole and 2-thioureidonaphtho [2′, 1′:4, 5] thiazole were obtained.View full abstractDownload PDF (740K) -

JOURNAL FREE ACCESSMorphine, its derivatives, and their acid salts can be titrated in anhydrous acetic acid with perchloric acid by glass-calomel electrode potentiometrically or with crystal violet as the indicator. Morphine and its derivatives can be determined accurately by the basicity of the methylamino group, and their hydrochloride can also by titrated with same accuracy by adding mercuric acetate more than the equivalent of the sample and the excess of mercuric acetate scarcely hinders the titration. The acidity of phosphoric and sulfuric acids partially augment that of anhydrous acetic acid, so that the determination of the phosphates and sulfates are not very accurate. Codeine sulfate can be titrated one mole as one equivalent, because the first dissociation of sulfuric acid is large, but the second is very small in anhydrous acetic acid. It is known from the titration curves, that the basicity of morphine, ethylmorphine, codeine, hydrocodeine, and 3, 6-diacetylmorphine is similar to each other, but that the basicity of thebaine is stronger than that in anhydrous acetic acid.View full abstractDownload PDF (668K) -

JOURNAL FREE ACCESSAntihistaminics of dimethylaminoethane derivatives can be titrated accurately by the basicities of the dimethylamino and other basic nitrogen group, with perchloric acid in anhydrous acetic acid, potentiometrically using glass-calomel electrodes or with crystal violet as the indicator. Hydrochlorides of Diphenhydramine, Tripelennamine, and Thonzylamine can be accurately determined by adding mercuric acetate more than the equivalent of the sample, but Anergen hydrochloride sometimes cannot be determined. Succinate of Doxylamine and maleates of Pyrilamine and Chlorprophenpyridamine can be directly titrated. Diphenhydramine and Anergen are determined one mole as one equivalent, and the others as two equivalents. It is known from this and the previous experiments that many organic acids do not hinder the titration of organic bases, and they hardly show their acidity in anhydrous acetic acid. It is supposed from the titration curves, that Doxylamine with the methylbenzylpyridine is a little stronger base than Diphenhydramine. Pyrilamine with the p-methoxy group is weaker than Tripelennamine, Chlorprophenpyridamine with the p-chlorobenzyl group is the weakest, and the two basic groups of Tripelennamine behave similarly in anhydrous acetic acid.View full abstractDownload PDF (734K) -

JOURNAL FREE ACCESSDiscrimination between Cinnamomum cassia and Cinnamomum Loureirii is difficult when their root bark, trunk bark, and branch bark are in a powder form. Their discrimination through capillary analysis was studied and it was found that the two can be discriminated easily by the following items:
1) When the γ-zone of the ethanolic image is spotted with 0.1% pyronin solution and observed under a filtered ultraviolet light, C. cassia shows orange fluorescence while the root bark of C. Loureirii is red. When the same solution is spotted on the non-β zone, both the trunk and branch barks of C. cassia and C. Loureirii show orange fluorescence while the root bark shows a red color.
2) When ether is spotted on the γ-zone of the ethanolic image of C. Loureirii, trunk and branch barks show orange color while the root bark does not show any coloration.
3) In the methylene blue-D-fication method, D-fication is effected in C. cassia by C. E. 1 solution, root bark of C. Loureirii by C. E. 2 solution, and trunk and branch barks of the latter by C. E. 3 solution.View full abstractDownload PDF (476K) -

JOURNAL FREE ACCESSA solution of 2, 4-dinitrophenylhydrazine in 1 N hydrochloric acid was reacted with a definite amount of a solution of carbonyl compounds to allow formation of a hydrozone, and the amount of 2, 4-dinitrophenylhydrazine before and after the reaction was measured by azotometry. The difference in these two values enabled the measurement of the amount of carbonyl compounds. The use of this determination method on several of the carbonyl compounds was found to give values agreeing well with the results obtained by other methods of determination.View full abstractDownload PDF (393K) -

JOURNAL FREE ACCESSTwo crystalline components, A and B, were isolated from the ether extract of the dried roots of Angelica pubescens (Umbelliferae), the original plant of the crude drug, Dokkatsu. Compound A comes as pale yellow, microneedle crystals of m.p. 304-306°, extremely sparingly soluble in water and organic solvents, and soluble in hot pyridine and glacial acetic acid. It gives a positive reaction to magnesium-hydrochloric acid reagent and does not form an acetyl derivative. Its infrared absorption spectrum revealed the presence of a δ-lactone and a double bond but showed no absorption of a hydroxyl. This compound is assumed to be a flavone homolog. Compound B came as white crystalline powder, m.p. 260°.View full abstractDownload PDF (140K) -
