Microwave‐assisted Regioselective Synthesis of Novel Bis(azoles) and Bis(azoloazines)

Microwave‐assisted Regioselective Synthesis of Novel Bis(azoles) and Bis(azoloazines)

We introduce efficient regioselective synthesis of a series of novel bis(pyrazoles) and bis(isoxazoles) via 1,3‐dipolar cycloaddition reaction under microwave irradiation. Unequivocal structural assignment of the obtained regioisomers was determined utilizing 1H‐13C HMBC NMR techniques as a valuable...

description We introduce efficient regioselective synthesis of a series of novel bis(pyrazoles) and bis(isoxazoles) via 1,3‐dipolar cycloaddition reaction under microwave irradiation. Unequivocal structural assignment of the obtained regioisomers was determined utilizing 1H‐13C HMBC NMR techniques as a valuable tool. A comparative study of the aforementioned reactions was carried out under conventional method as well as under microwave irradiation conditions.
