Efficient synthetic method for the preparation of ethyl 2-aryl-2,3-alkadienoates through Pd-catalyzed selective allenyl cross-coupling reactions of aryl iodides with organoindiums generated in situ from indium and ethyl 4bromo-2-alkynoate was developed. The cyclization reaction of ethyl 2-aryl-2,3-alkadienoates catalyzed by AuCl3 and AgOTf in the presence of AcOH or TfOH produced various α-aryl γ-butenolides or γ-substituted αaryl γ-butenolides.
