摘要：
A new three-component strategy for the efficient synthesis of 2,3,5-trisubstituted thiophene derivatives through a [2+2+1] heterocyclization between 3-(2-aryl-2-oxoethylidene)-2-oxindoles and -thiocyanato ketones under microwave irradiation is described. The bond-forming efficiency, accessibility, and generality of this synthesis make it highly valuable to assemble thiophene scaffolds.
