Interaction of 2-(2-azahetaryl)-3-oxo-4-chlorobutane nitriles with esters of aromatic amino acids

The reaction of 2-(2-azahetaryl)-3-oxo-4-chlorobutane nitriles with esters of aromatic acids was studied. A series of 1H,4H-3-(2-azahetaryl)pyrrolo[1,2-a] quinazoline-2,5-diones and 1-aryl-2-amino-3-(2-azahetaryl)-4-(5H)-oxopyrroles was obtained. The reaction of the latter with hydrazine and acetic anhydride was investigated. Taras Shevchenko Kiev University, Kiev 252033, Ukraine.
