Palladium and acid cooperative catalysis is presented as a strategy for the [3 + 2] cycloaddition of acceptor/donor-type diazo compounds with terminal alkynes. The [3 + 2] cycloaddition of α-aryl-α-diazoacetates with terminal alkynes proceeded smoothly to produce 2,3,5-trisubstituted furans with high yields. This synthesis method provided a direct and efficient pathway to prepare furan ring-containing
