摘要:
Hydrolysis of 4-heteryl-3-methoxycarbonyl-2-pyrrolidones in an alkaline medium and subsequent decarboxylation of the resulting 2-pyrrolidine-3-carboxylic acids afforded 4-(pyrid-3-yl)- and 4-(1-methylbenzimidazol-2-yl)-2-pyrrolidones.

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.
