An Aldol-Based Approach to the Synthesis of the Antibiotic Anisomycin

Abstract

[reaction: see text] A new approach to the synthesis of the antibiotic anisomycin is reported that relies upon a key aldol disconnection. The glycolate aldol coupling proceeds in 75% yield and with >95% diastereoselectivity, which allows the 13-step synthesis to proceed in 35% overall yield.
