Proceeding from reactions of methyl 4-aryl(hetaryl)-2-oxopyrrolidine-3-caroxylates with hydrazine and phenylhydrazine a series of hydrazides of the corresponding 2-oxopyrrolidine-3-carboxylic acids was obtained combining in the molecule a lactam ring and carbohydrazide groups. Phenylhydrazides of 2-oxopyrrolidine-3-carboxylic acids possess the Z-configuration.
