摘要

Abstract A number of 2-aryl-substituted pyrido [3, 2-e] and [4, 3-e][1, 2, 4] triazolo [1, 5-c] pyrimidines and [1, 2, 4] triazolo [1, 5-c] pteridines 11, 12a, b, e, their corresponding 5- carbonyl derivatives 7, 8a, b, e and some pyrimido [5, 4-e][1, 2, 4] triazolo [1, 5-c] pyrimidin-5- ones 7, 8c, d have been synthesized, according to different pathways. The new tricyclic heterocycles were prepared with the aim of studying their possible benzodiazepine ...
