We have developed, highly efficient, one-pot, solvent-free, [Et3NH][HSO4] catalyzed multicomponent reaction protocol for the synthesis of 1,3-thiazolidin-4-ones in excellent yields. For the first time, the 1,3-thiazolidin-4-ones were evaluated in vitro for their antimycobacterial activity against Mycobacterium tuberculosis dormant MTB H37Ra and Mycobacterium bovis BCG strains. Among the synthesized

A one-pot, multi-component, green, and highly efficient procedure has been developed for synthesis of 4-thiazolidinones. Use of β-cyclodextrin-SO3H as an eco-friendly and recyclable catalyst resulted in excellent yields under solvent-free conditions. This procedure has the advantages of readily available starting materials, short reaction times, high yields, easy workup, broad substrate scope, and use of an environment-friendly catalyst. The catalyst can be recycled with slight loss of its catalytic activity.

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.
