Mesoporous MCM-41-supported Schiff base and CuSO4?5H2O (MCM-41@Schiff base-CuSO4?5H2O) catalyzed one-pot three-component condensation of cyclic ketones, amines and thioglycolic acid in toluene. And a series of corresponding spiro thiazolidinone derivatives were obtained in high yields (up to 97%). The synthesized catalyst was characterized via FT-IR, XRD, SEM, TEM and EDS and can be easily recovered by centrifugation and reused at 10 times without any change in catalytic activity. Moreover, the scale-up experiment also demonstrated the practicability of the catalytic system on the condensation. The possible mechanisms pave the way to investigation on the reactions of other cyclic ketones with thioglycolic acid.

The use of 3-substituted-2-mercaptoacrylic acids, synthesized via hydrolysis of 5-ylidenerhodanines for the preparation of 2,3,5-trisubstituted-4- thiazolidinones via a new variant of the one-pot, three-component reaction has been studied.
