A convenient method was developed for the synthesis of N-substituted rhodanines based on the reaction of amines, hydrazides, or acid thiohydrazides with trithiocarbonyl diglycolic acid in the presence of dicyclohexylcarbodiimide or 1,1¢-carbonyldiimidazole.

Dedicated on the occasion of the jubilee of academician Irina P. Beletskaya AbstractThe cycloaddition reaction of 5-arylidene rhodanine derivatives with dienophiles under microwave irradiation afforded the title compounds within short reaction times and in good yields.

Thiazole derivatives R 0260Synthesis of Fused Heterocyclic Compounds on the Basis of 2-Thioxo-1,3-thiazolidin-4-ones. -Convenient synthetic approaches to various heterocyclic compounds are based on rhodanine derivatives [(I), (V), and (XV)]. Reactions of 5-arylmethylidene-substituted rhodanines (V) and (XV) with malononitrile derivatives are accelerated under microwave irradiation. -(YAROVENKO, V. N.; NIKITINA, A. S.; ZAVARZIN, I.
