nanoparticles (Pd NPs: ~5-nm diameter) catalysed an efficient, solvent-free protocol for the cyclocondensation reaction of the aldehydes, anilines and mercaptoacetic acid has been developed. This method offers a rapid, relatively economical and ecofriendly protocol for the synthesis of 2,3-disubstituted-4-thiazolidinones for the first time. Moreover, the catalyst can also be easily recovered and recycled with

A convenient one-pot, rapid and scalable synthetic protocol has been developed for recently reported anti-inflammatory agents, thiazole-substituted pyrazolyl-4-thiazolidinones. Quantitative multicomponent cyclocondensation of 3-(4-methyl-2-substituted thiazol-5-yl)-1-phenyl-1H-pyrazole-4-carbaldehydes (5a, b), amines and mercaptoacetic acid has been carried out in safer medium, diisopropylethylammonium acetate, at room temperature. The optimisation details of the developed novel protocol are recorded.
A visible-light-induced, one-pot mild and efficient, multicomponent-tandem synthesis of diversified 1,3-thiazolidin-4-ones under catalyst and solvent-free conditions is reported. Here, visible-light, an ideal source of energy, has been used as photochemical activator to generate CN and CS bonds under radical mechanistic pathway from aromatic amines, aldehydes and thioglycolic acid. The reported methodology
