オレフィン環化反応

テルペノイドの閉環

抄録

Biomimetic cyclization reactions of acyclic isoprenoids and their derivatives were surveyed, following the classification, 1) those starting at the head part of acyclic precursor and simulating higher terpenoid biosynthesis, 2) those activated at the tail part and imitating lower terpenoid biogenesis. The application of these reactions to the synthesis of some natural products was also reviewed.
