Abstract

A concise formal synthesis of stemoamide (1) and its 9a-epimer 14 in 5 steps is described featuring a cascade cyclization triggered by imine formation. A good selectivity for either epimer is readily accomplished by variation of the ester (9b or 9a, respectively) and the reaction conditions. (C) 2015 Elsevier Ltd. All rights reserved. (AU)
