Total synthesis of marine-derived azole resistant antifungal agent (-)-melearoride A and antibiotic (-)-PF1163B

Abstract

A flexible stereoselective and convergent cum divergent approach to the synthesis of two 13-membered macrolides through a common skeleton present in their structure is described in two different routes, with good overall yield. The key synthetic reactions utilized include Keck allylation, Evans asymmetric methylation, Grubbs metathesis and Julia-Kocienski olefination reaction.
