A series of novel s-triazolothiadiazoles 3a-h were prepared by condensation reaction of substituted amino triazoles 1a-b with N-phethaloyl-L-amino acids 2a-d in the presence of the phosphoroxy chloride （POC13） as an...A series of novel s-triazolothiadiazoles 3a-h were prepared by condensation reaction of substituted amino triazoles 1a-b with N-phethaloyl-L-amino acids 2a-d in the presence of the phosphoroxy chloride （POC13） as an anhydrous reagent. The structure of all synthesized compounds was confirmed by IR, 1H NMR, arid 13C NMR spectroscopy.展开更多
