Synthesis of some functionalized arylaminomethyl-1 ,2,4-triazoles, 1,3,4-oxa- and thiadiazoles

Abstract

Thiosemicarbazides undergo different cyclization reactions to give five membered heterocycles. The product of cyclization depends on the reagent used. This cyclization leads to the formation of 1,3,4-oxadiazole, 1,3,4-thiadiazole and 1,2,4-triazole derivatives. The reaction of thioglycolyl hydrazide derivatives of the 1,2,4-triazole compounds was discussed. The activity against hepatitis B virus (HBV) has been tested.
