Abstract

A mild, convenient, and efficient one-pot synthesis of amino-1,3,4- oxadiazoles is described. In situ preparation of various thiosemicarbazides by the reaction of different carboxylic acid hydrazides with trimethylsilyl isothiocyanate (TMSNCS), followed by cyclodesulfurization of thiosemicarbazides under basic conditions in the presence of I2/KI resulted in 2-amino-1,3,4-oxadiazoles in high yields (79-94%).
