Abstract
2-Substituted hydrazinecarbothioamides and N,2-disubstituted hydrazinecarbothioamides react, in high yields with dimethyl acetylenedicarboxylate to give 4-oxo-Z-(thiazolidin-5-ylidene)acetate derivatives. Several mechanistic options involving interaction are presented. The structures of thiazolidin-4-ones have been unambiguously confirmed by single crystal X-ray crystallography.
