Homoleucinol誘導体 (第2報)

抄録

Attempt was made to prepare N-dimethyl and N-monoisopropyl derivatives of homoleucinol. p-Nitrobenzoyl derivative of the OH group in N-isopropylhomoleucinol was obtained but not that of the NH group. L-Compound of N, N-diethylleucinol p-aminobenzoate was obtained as an oil of b. p. 170°, [α]_D²⁴+15°. Infrared spectrum of 2, 5-dimethyl-4-isobutyloxazole was measured and the absorptions at 1646 and 1586cm^-1 were considered to be those of conjugated C=C and C=N, respectively.
