Mesoporous MCM-41 supported Schiff base and CuSO4·5H2O shows high catalytic activity in the cyclocondensation of mercaptoacetic acid with imines (or aldehydes and amines) to afford pharmaceutically important thiazolidinone derivatives. The catalytic reactions involving two-components or three-components afforded the desired product in high yields (up to 98% and 99%). Moreover, the catalyst works well with respect to recyclability, giving the product in 85% and 83% yields after recycling six times.
