Rubazonic acids are a class of dyes that are long-known, but studies on their syntheses and uses are rare. We now describe an experimentally simple and highly practical one-pot procedure for their synthesis starting from easily accessible 1H-pyrazol-5(4H)-ones. This protocol provides direct access to a broad range of the desired rubazonic acid derivatives through oxidative diazidation combined with

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.

assembled from diverse o-haloaryl ynones and β-bromoalkenyl ynones via base mediated, one-pot, metal free, orthogonal strapping (tethering) mediated by the recursive anion(s) derived from pyrazolones. These convenient, preparatively useful transformations proceed through either a tandem Michael addition–intramolecular SNArreaction or a tandem Michael addition–intramolecular AdNE process to furnish
