The total syntheses of (−)‐rotenone and (−)‐dalpanol have been achieved by a group‐selective, stereospecific 1,2‐shift of an epoxy alcohol and SNAr cyclizations. Three oxacycles are constructed, thus illustrating a versatile synthetic route to various rotenoids.
(-)-鱼藤酮和(-)-丹酚的总合成是通过对环氧醇进行的基团选择性立体定向1,2-移位和S N Ar环化实现的。构造了三个氧杂环,从而说明了合成各种类胡萝卜素的通用途径。
