Abstract
A highly stereoselective synthesis of [(S)-coriolic acid] (1) and first total synthesis of (S)-15,16-didehydrocoriolic acid (2) by a Pd°-CuI catalysed coupling of (S )-halovinylalcohol with acetylenic moiety is described. The required optically pure chlorovinylalcohols or bromovinylalcohols have been prepared from epoxy chlorides, obtained by Sharpless asymmetric epoxidation of allylic alcohols.
