An alternate synthesis of sporiolide B from (R)-glyceraldehyde

Abstract

In this article, a novel synthetic route was described for the total synthesis of Sporiolide B from inexpensive and commercially available starting materials by a concise fourteen-step sequence in 6.50% overall yield. This convergent synthesis utilizes Grignard reaction, Asymmetric dihydroxylation, Yamaguchi macrolactonization and ring closing metathesis as the key steps.
