    テルペン, ステロイドを始め天然物の合成に今日各種の金属錯体がよく用いられる。この分野の発展は目ざましく数多くの総説が現れている。ここでは主として遷移金属錯体を用いるテルペン類の合成をとりあげる。セスキテルペンは一部にとどめた。このように限っても数多くの報告はこの小文にまとめきれない。そこで筆者らが進めている実用的な合成に焦点をあてることにする。すなわちイソプレンあるいは化学原料としてかなり豊富に利用できるテルペンを利用する合成とそれらに関連する反応を取りあげることにした。

    Recent developments related to the total syntheses of spermidine and spermine alkaloids are reviewed. Those alkaloids are kukoamine A 11, maytennine 30, celacinnine 31, celallocinnine 32, celafurine 33, celabenzine 34, dihydroperiphylline 35, (±) -dihydropalustrine 73, 75, lunarine 76, lunaridine 77, codonocarpine 79, and (-) -homaline 93. This article is constructed by following chapters : (i) acyclic spermidine and spermine alkaloids, (ii) macrocyclic spermidine alkaloids, (iii) macrocyclic spermine alkaloids, (iv) observations on biosyntheses, and (v) new synthetic methods of macrocyclic aminolactams.

    Recent advances in the synthesis of the propellanes are reviewed. This article is divided into two parts, Part 1 concerns the available synthetic methods for a variety of propellanes in which the methods are classfied by the type of reactions ; 1) cycloaddition, 2) condensation, 3) reductive dehalogenation and 4) skeletal rearrangement. Part 2 deals with the synthesis of the target propellanes which involve small ring propellane, 1, 4-bridged Dewar benzene, buttaflane, trispiro- [3, 3, 3] -propellane and modhephene.

    Azulenes are of interest in their chemical and physical properties as one of the fundamental nonbenzenoid aromatic compounds. The present article provides a summary of a new synthetic method of azulene derivatives by the reaction of 2H-cyclohepta [b] furan-2-ones with enamines developed mainly in the author's laboratory. This method could be applied to the syntheses of azulene derivatives having alkyl, aryl, and functional substituents, and of polycyclic aromatic compounds containing azulene ring.

    The present article involves the studies on aroma constituents of turkish tobacco and the sex pheromone of cigarette beetle, of which the former is considered to be the biologically active substances to human and the both are to the insect.
    A comprehensive investigation of aroma constituents of Turkish tobacco showed the existence of terpenoid acids related to tobacco thunberganoids. The degradation of thunberganoids to these terpenoid acids are considered to be closely related to the formation of the tobacco characteristic aroma.
    In the course of our another studies on the biologically active substances to cigarette beetle, a serious pest of cured tobacco leaves, a sex pheromone, 4, 6-dimethyl-7-hydroxynonan-3-one (serricornin) and other 4, 6-dimethylnonane derivatives as minor components were isolated. The presence of these 4, 6-dimethylnonane derivatives suggests that these pheromone components are derived from the polyketide biosynthesis.
    These biologically active substances were synthesized in practical scale and now the applications of these chemicals as tobacco flavors and the attractants of cigarette beetle are in progress.

    Dye laser is a very useful device for some chemical applications such as spectroscopy, laserinduced chemical reaction, and picosecond flash-photolysis, because it generates a coherent radiation with a very wide tunable range from 311 nm to 1285 nm. More than 500 kinds of fluorescent organic chemicals show laser action under intense excitation by a flashlamp or other lasers. In this review, a fundamental principle and characteristics of dye lasers are described. Then, useful and efficient chemicals used for dye lasers are reviewed. Most important classes of dye laser materials are polymethine dyes, xanthene dyes, oxazine dyes, coumarin derivatives, stilbene derivatives and p-origophenylenes.

    Oxyselenation reactions, which involve an electrophilic attack of organoselenium group on olefin and acetylene followed by a nucleophilic attack of oxygen atom of alcohol, carboxylic acid, water etc, are reviewed, especially focusing on the recent application to organic synthesis. The term of solvoselenation is introduced for the first time as a more general name for the oxyselenation type reaction in various solvents such as ROH, RCO2 H, RCN etc.

    炭素-炭素不飽和結合の位置を移す異性化反応は酸, 塩基, 遷移金属錯体などを触媒として数多く研究されており, それぞれの触媒系の特長, 適用限界が明らかにされている。このうち, 遷移金属の塩または錯体は, ほぼ中性の条件下で反応を進行させることができるため副反応を起こしにくいという特長があり, 種々の官能基をもつ不飽和化合物の異性化には好都合である。最近, 著者らは二重結合移動反応を積極的に有機合成に役立てるという意図で研究を進めており, ルテニウムヒドリド錯体が, 安価でかっ簡便に利用できる有効な触媒であることを見出した。ここではその調製法, 性質, 反応基質に対する適用限界を含め, 適用例を紹介したい。
