Abstract

The lithium diethylamide induced rearrangement of a series of propylidenecycloalkane oxides to allylic alcohols exhibits marked regioselectivity, with endocyclic olefin product being formed preferentially. An exception is propylidenecyclohexane oxide which gives 95% of the alternate, tertiary allylic alcohol. A series of ethylidenecycloalkane oxides, where preference for endocyclic elimination competes with proton abstraction from primary ...
