Abstract
A facile and general procedure is presented for the one-pot synthesis of 2-aminotetrahydrothiopyrano[4,3-b]pyran-3-carbonitrile derivatives. It is based on the three-component condensation of aliphatic, aromatic, or heterocyclic aldehydes, malononitrile, and thiopyran in the presence of mesoporous amino-functionalized MCM-41 silica in ethanol. This efficient technique has the advantage of giving 2-aminotetrahydrothiopyrano[4,3-b]pyran-3-carbonitrile derivatives using a heterogeneous mesoporous reagent in high yields, in short reaction times, and offers a simple product isolation procedure.
