The reaction of (2,2-dimethylhydrazino)succinic acid ester with allyl and phenyl isothiocyanates leads to esters of 1-substituted (3-dimethylamino-5-oxo-2-thioxo-4-imidazolidinyl)acetic acids, which in protic solvents undergo a slight degree of elimination of dimethylamine to give esters of 1-substituted (5-oxo-2-thioxoimidazolidin-4-ylidene)acetic acids.The structure of methyl (1-allyl-5-oxo-2-thioxoimidazolidin-4-ylidene)acetate was proved by x-ray diffraction analysis.
