Abstract

A new synthetic route to polycyclic homocyclopropylcarbinols has been realized by lithiation of bromocyclopropyl epoxides with n-butyllithium and subsequent intramolecular attack of the metalated cyclopropane ring onto the epoxide. A series of seven bromocyclopropyl epoxides was prepared from diene precursors in three or four steps by dibromocyclopropanation, epoxidation, and stereoselective reduction of one bromine ...
