40. Diazoaldehyde chemistry: Part 3. Synthesis of 4-acyl-1H-1,2,3-triazole derivatives

Ten 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.
