Synthesis of some novel pyrazolopyridooxazine, pyrazoloquinolizines, pyrazoloindolizine and pyrazolopyranopyrimidinone derivatives

Abstract

Different pyrazolone derivatives were prepared as starting materials for the synthesis of pyrazolopyridooxazine, pyrazoloquinolizines, pyrazoloindolizine, 1,4-oxazinopyrazolines and pyrazolopyranopyrimidinone derivatives via reactions with different reagents applying the one pot multicomponent reaction using microwave and ultrasound irradiation in some cases.
