摘要

Abstract This paper describes the synthesis of the previously unknown 11H-1, 2, 4-triazolo [4, 3-b] pyridazino [4, 5-b] indoles (2) and 11H-tetrazolo [4, 5-b] pyridazino [4, 5-b] indoles (3) from 4-hydrazino-5H-pyridazino [4, 5-b] indoles (1), as well as the synthesis of 1, 2, 4- triazolo [3, 4-f]-1, 2, 4-triazino-[4, 5-a] indoles (10) from 2-indolecarbohydrazide (4). Compounds 2 were obtained by acylation of compounds 1, followed of thermal cyclization ...
