フェニルピルビン酸オキシムを基本骨格とする海洋生物由来の生物活性物質の化学

抄録

Natural products, isolated as secondary metabolites of such marine origins as sponge, alga and sea hare, have served new and various structures with a variety of bioactivity. Since 1970, the phenylpyruvic acid oxime derivatives have widely been isolated as a main group of marine natural products containing bromine atoms. This family has potent bioactivities such as antimicrobial, antitumor, antifeedant activities, and so on. Synthetic studies on phenylpyruvic acid oxime derivatives are described. Among them, the phenolic oxidation has been recognized as one of important methods to synthesis of bastadines and spiroisoxazolines.
