Abstract
During acylation of 7-isonicotinoyl-6,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-one or its alkylation followed by treatment with organic bases, spirocyclization occurs with formation of derivatives of a novel heterocyclic system: 1′-acyl-and 1′-alkylspiro[7H,12H-6a,11b-diazabenz[e]aceanthrylene-6(5H),4′(1′ H)-pyridine]-5,7-diones. We have studied the spectral properties of the synthesized spirans. We have shown that 7-nicotinoyl-6,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-one does not undergo an analogous reaction of repeated acylation, while treatment of its quaternary salt with bases leads to a complex mixture of unidentified products.
