A short stereoselective synthesis of (+)-(6R,2′S)-cryptocaryalactone via ring-closing metathesis

Abstract

A short stereoselective synthesis of (+)-(6R,2′S)-cryptocaryalactone was successfully completed. Key steps included the application of Carreira’s asymmetric alkynylation reaction to form a propargylic alcohol and subsequently lactone formation using the powerful ring-closing metathesis reaction.
