An expedient synthetic procedure of gamma-alkylidenebutenolides was developed via a sequential indium-mediated Barbier-type reaction of Morita-Baylis-Hillman bromide with aldehyde, lactonization, and double-bond isomerization. Various gamma-alkylidenebutenolides including bovolide and its derivatives were synthesized in good overall yields. (C) 2011 Elsevier Ltd. All rights reserved.
