Total Syntheses of Anti-HIV Cyclodepsipeptides Aetheramides A and B

J Org Chem. 2016 Dec 16;81(24):12466-12471. doi: 10.1021/acs.joc.6b02292. Epub 2016 Nov 28.

Abstract

A concise total synthesis of aetheramide A in an overall yield of 4.7% with a longest linear sequence of 15 steps is described. This synthetic strategy features macrocyclization via an intramolecular trapping of acylketene generated from dioxinone precursor, and stereoselective late-stage methylation of β-ketoamide. Aetheramide B could be synthesized via the ester migration of aetheramide A.
