Synthesis of some new pyridones, fused pyrimidines, and fused 1,2,4-triazines

Abstract

(Chemical Equation Presented) Cyclocondensation of hydrazides, 3-aminopyrazoles, 3-amino-1,2,4-triazole, 2-aminobenzoimidazole, pyrazole-3-diazonium salts, 1,2,4-triazol-3-diazonium salt, or benzoimidazole-2-diazonium salt with sodium salt of 3-hydroxy-1-(2-naphthyl) prop-2-en-1-one gave 2-pyridones, pyrazolo[1,5-a]pyrimidines, triazolo[1,5-a]pyrimidine, benzo[4,5]imidazo[1,2-a]pyrimidine, (pyrazolo[5,1-c][1,2,4]triazin-3-yl)-methanone, [1,2,4]triazolo[5,1-c][1,2,4] triazin-3-yl-methanone, or benzo[4,5]imidazo[2,1-c] [1,2,4]triazin-3-yl- methanone derivatives, respectively, which will be tested for anti-tumor and anti-cancer activates. © 2010 HeteroCorporation.
