First stereoselective total synthesis of macrocarpal C: structure elucidation of macrocarpal G

Abstract

The first stereoselective total synthesis of macrocarpal C is achieved via a coupling reaction of a silyl dienol ether with a novel hexasubstituted benzene chromium tricarbonyl complex as an optically active benzyl cation equivalent, thereby clarifying the identity of macrocarpal C and G.
