资源简介：
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 AuI/AuIII redox cycle has been proposed with Selectfluor acting as the external oxidant.
