A gold(I)-catalyzed protocol for intermolecular 1,6-conjugate addition of nucleophilic allenol ester generated in situ through [3,3]-sigmatropic rearrangement with p-quinone methides (p-QMs) has been developed. The gold catalyst plays a dual role by the acid-triggered activation of alkynes and at the same time as a Lewis acid for activation of p-QMs toward nucleophilic attack. This method enables rapid access to a wide range of densely functionalized diarylmethine-substituted enones, a Morita-Baylis-Hillman (MBH) product with high selectivity, excellent yields, and broad substrate scope.

Indium chloride catalyzed alkylative rearrangement of propargylic acetates into α-alkyl-α,β-unsaturated carbonyl compounds has been achieved. Propargylic acetates functioned as α-acylvinyl anion equivalents to react with carbocations generated from alkyl
