Abstract

Hyperforin has remained a popular and challenging synthetic target since its isolation over forty years ago. As a result, numerous synthetic strategies and ring-forming reactions have been developed to address its formidable molecular architecture. Herein we describe our contributions to this area resulting in a ten-step synthetic pathway enabled by a novel diketene annulation reaction and oxidative ring expansion strategy.
