synthesis of (−)hibaene 1 is described. The key steps are a photochemical cycloaddition of vinyl acetate on the α-β unsaturated ketone 2 and a Wagner-Meerwein type rearrangement of the diols 14 and 15, which contain a highly strained cyclobutane ring. A selective esterification of the rearranged diols 22a or 22b leads to intermediates which can conveniently be transformed into (−)hibaene.
描述了(-)hibaene 1的全合成。关键步骤是乙酸乙烯酯在α-β不饱和酮2上的光化学环加成反应,以及二醇14和15的Wagner-Meerwein型重排,其中二醇14和15含有高度应变的环丁烷环。重排的二醇22a或22b的选择性酯化产生可以方便地转化为(-)hibaene的中间体。
