Abstract
It has been established that the reaction of 2,3-dioxopyrrolo[2,1-a]isoquinolines with hydrazine occurs at the lactam carbonyl with fission of the pyrroledione ring and the formation of enaminoketohydrazides, the structure of which was confirmed by x-ray crystallographic and spectral data on these compounds and their derivatives (hydrazones).
