A preparative procedure has been developed for the synthesis of substituted 5,7-dihydropyrrolo-[3,4-d][1,2]diazepines by recyclization of 6-phenylpyrano[3,4-c]pyrrol-4(2H)-one with hydrazine hydrate. The stability of the seven-membered ring in the products under acidic conditions, alkylation, and heteroring fusion to the diazepine ring have been studied.

4-c]pyridines were developed based on cyclization of 3-phenacyl-4-ethoxycarbonyl(acetyl)pyrrole derivatives reacting with N-methylformamide or formamide, and also on recyclization of pyrrolo[3,4-c]pyryliumsalts under the action of ammonium acetate and hydrazine acetate. The influence of substituents in initial reagents on composition of reaction products was studied.
