Stereoselective synthesis of (-)-spicigerolide

J Org Chem. 2009 Mar 6;74(5):2008-12. doi: 10.1021/jo8025753.

Abstract

(-)-Spicigerolide was stereoselectively synthesized from a protected (S)-lactaldehyde. The synthesis of the polyacetylated framework relied on two Zn-mediated stereoselective additions of alkynes to aldehydes as well as a regiocontrolled [3,3]-sigmatropic rearrangement of an allylic acetate. The pyranone moiety was constructed via ring-closing metathesis.
