An efficient total synthesis of a potent antifungal and moderate cytotoxic agent crocacin C is described. The synthesis involves the generation of four contiguous stereogenic centres via desymmetrization of a meso bicyclic dihydrofuran using asymmetric hydroboration. (c) 2006 Published by Elsevier Ltd.

A formal synthesis of crocacin C is described proving the versatility of Prins cyclization in natural product synthesis. The approach is convergent and highly stereoselective. Cross-metathesis and Heck reactions were utilized for the insertion of an aromatic group in a stereocontrolled manner.
