A facile two-step synthesis of 2,4-dihydro-5-amino-[1,2,4]triazol-3-ones is described. Firstly, 1,3-disubstituted thioureas reacted with bis(trichloromethyl) carbonate (BTC) in the presence of a base such as NaHCO3 to form the intermediate 4-(a
An efficient synthesis of 1,3,4-oxadiazoles from N,N′-diacylhydrazines using Ph3P·Br2, Ph3P·CCl4 or Ph3P·CBr4 adducts as condensing agents

1,3,4-Oxadiazoles including 2-amino derivatives were effectively synthesized by treatment of N,N′-diacylhydrazines or N-acylsemicarbazides with Ph3P·Br2, Ph3P·CCl4 or Ph3P·CBr4 adducts in the presence of Et3N in CH2Cl2 under mild conditions.
