AbstractAn efficient organocatalytic approach for the synthesis of 1,3-oxathiolanes and 1,3-thiazolidines is reported. In this methodology, conjugated base of nitromethane was employed as a potential organocatalyst to promote cyclization reaction between strained heterocyclic compounds and heterocumulenes at ambient conditions.

A FeCl3-catalyzed [3 + 2] cycloaddition reaction of aziridine with isothiocyanate was developed. The cycloaddition reaction was completed in two minutes with high chemoselectivity, stereoselectivity. 15 (tosylthiazolidin-2-ylidene)anilines were obtained with moderate to excellent yields.

Aziridines underwent cyclization reaction with carbon disulfide and isothiocyanate in the presence of organophosphine to afford thiazolidinone derivatives in good to high yields. The mechanistic study revealed that organophosphine serves as a catalyst in the reaction.

An efficient synthesis of 1,3-thiazolidine derivatives has been achieved in which 2-pyridinecarboxaldehyde oxime was employed as a base catalyst to effect cyclisation between aziridines and CS2 in DMF at 40 °C. A similar reaction between aziridines and thiocyanates yielded 1,3-thiazoline-2-imine derivatives
