Synthesis of highly substituted γ-butyrolactones by a gold-catalyzed cascade reaction of benzyl esters

Abstract Easily accessible benzylic esters of 3-butynoic acids in a gold-catalyzed cyclization/rearrangement cascade reaction provided 3-propargyl ?-butyrolactones with the alkene and the carbonyl group not being conjugated. Crossover experiments showed that the formation of the new C?C bond is an i...
