  One-Step Synthesis of Tetrazolo[1,5-a]pyrimidines by Cyclization Reaction of Dihydropyrimidine-2-thiones with Sodium Azide

  摘要：

  An novel, versatile and cost-effective approach for tetrazolo[1,5-a]pyrimidines and tetrazolo[1,5-a]quinazolines from cyclization reaction of dihydropyrimidinethiones with sodium azide in the presence of mercuric acetate is described. To compare this procedure with the conventional method, we carried out the cyclization reactions through direct functionalization of the pyrimidinethione core, which obtained from Biginelli 3,4-dihydropyrimidine-2-thiones or 4-aryl-7,7-dimethyl-5-oxo-1,2,3,4,5,6,7,8-octahydroquinazoline-2-thiones.
