A water mediated and thiamine hydrochloride catalysed eco-compatible efficient method was developed for the synthesis of spiro[acenaphthylene-1,2 0 [1,3]-thiazolidine]-2,4 0 (1H)-diones via multi-component reaction of acenaphthylene-1,2-dione, substituted anilines, and a-mercaptocarboxylic acid at 80°C temperature. This transformation involves the formation of two C-N bonds and one C-S bond leading to the creation of a five-member ring in a one-pot operation. Easy availability and recovery of the catalyst, no toxic/organic solvents, and high yield of product make the protocol attractive, sustainable, and economic.

Surfactant Aided Lewis Acids (LASCs) make an appearance as one of the efficient and substantial heterogeneous catalysts. Recently, various LASCs have been used as green and heterogeneous catalysts in organic synthesis due to their high water stability, recyclability, cost-effective nature and their ability to create stable colloidal dispersions. In the present review, we have discussed a variety of carbon-carbon bond forming, ring opening, addition and multi-component reactions for the synthesis of various biologically important heterocyclic compounds that have been successfully catalyzed by LASCs. In most cases, the catalytic activity of LASCs was found to be better in water in comparison to other organic solvents, which attracts special attention towards the present review.
