Abstract

An enantioselective route to the key intermediate leading to (+)-vernolepin, an antitumor sesquiterpene, isolated from Vernonia hymenolepis, has been developed starting from the chiral building block having a bicyclo[3.2.1]octane framework accessible by either enzymatic or catalytic kinetic resolution.
