Diazoaldehyde Chemistry. Part 3. Synthesis of 4‐acyl‐1H‐1,2,3‐triazole derivatives

Abstract

AbstractTen new α‐diazo‐β‐oxoaldehydes were condensed with aniline, ammonia, hydroxylamine, and semicarbazide to yield new 4‐acyl‐(1‐substituted)‐1H‐1,2,3‐triazoles in moderate‐to‐good yields. The method is simple and regiospecific. The latter feature makes this method superior to the widely used acylacetylene + azide approach.
