A simple and efficient general approach to various tetracyclic 6,7-dihydroquinazolino(3,2- a)(1,5)benzodiazepin-13(5H)-ones has been demonstrated by reductive N-heterocyclization of 5- alkyl- or benzoyl-1-(2-nitrobenzoyl)-1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-2-ones. These 2- nitrobenzoylamides were obtained by acylation of the starting 5-alkyl- or benzoyl-1,5- benzodiazepin-2-ones with 2-nitrobenzoyl chloride. A theoretical understanding of the features of the reductive N-heterocyclization reaction was provided by means of quantum chemical reactivity descriptors calculations.

A combined experimental and theoretical study of the synthesis of quinazolino[3,2-a][1,5]benzodiazepin-13-ones
