Abstract

Abstract In carrying on our interest in heteropolycyclic structures with biological activities, we projected the preparation of compounds containing the pyrido [3, 2-e][1, 2, 4] triazine or pyrido [2, 3-b][1, 4] triazepine systems. The established synthetic approach for the preparation of latter system led to the triazine derivatives 5a-f while a new bicyclic triazepine structure 6 is accomplished with difficulty.
