Reactions of New N-(2,2-Dichloro-1-cyanoethenyl)amides with Aliphatic Amines

The reaction of the newly synthesized N-(2,2-dichloro-1-cyanoethenyl)prop-2-enamide and 4-chloro-N-(2,2-dichloro-1-cyanoethenyl)butanamide with methylamine or dimethylamine gave rise to previously unknown 5-amino-1,3-oxazole-4-carbonitriles. In the case of the reaction of N-(2,2-dichloro-1-cyanoethenyl)amides with ethylenediamine diacetate, new (Z)-2,3,5,6,7,8-hexahydro-7-oxo-1H-imidazo[1,2-a][1,4]diazepine-9-carbonitrile and 4-chloro-N-(cyano(imidazolidin-2-ylidene)methyl)butanamide were obtained.
