摘要： Mesoporous MCM-41-supported Schiff base and CuSO(4)Greek ano teleia5H(2)O (MCM-41@Schiff base-CuSO(4)Greek ano teleia5H(2)O) 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.
