Abstract

Abstract Some [1, 2, 4] triazolo [1, 5-c] quinazolin-5 (6H)-ones 7, the corresponding isomers [1, 2, 4] triazolo [4, 3-c] quinazo-lin-5 (6H)-ones and the 5-amino derivatives 8, 9 and 11 have been synthesized starting from the acylamidrazones 5. The preparation of 5H-[1, 2, 4] triazolo [1, 5-d]-1, 4-benzodiazepin-6 (7H)-ones 15 and of 5-cyclicaminomethyl-[1, 2, 4] triazolo [1, 5-c] quinazolines 16 and 17 is also reported.
