Abstract

A gold(I)-catalyzed cascade cyclization-oxidative cross-coupling process has been applied to prepare β-alkynyl-γ-butenolides directly from allenoates and various terminal alkynes. Following an initial gold-catalyzed C-O bond forming allenoate cyclization, a mechanism based on a Au I/AuIII redox cycle has been proposed with Selectfluor acting as the external oxidant. © 2010 American Chemical Society.
