Solvent-dependent copper-catalyzed synthesis of pyrazoles under aerobic conditions

We present a copper-catalyzed oxidative cyclization of β,γ-unsaturated hydrazones, utilizing molecular oxygen as a stoichiometric oxidant. The methodology provides distinct classes of pyrazoles simply by changing the reaction solvent. Tris-substituted pyr

1,3-Dipolar Cycloaddition Reactions of Nitrile Oxides and Nitrile Imines with 2-Methoxyvinyl Phenyl Ketone

Nitrile oxides react regioselectively with 2-methoxyvinyl phenyl ketone 1 to give 4-benzoylisoxazoles 4 via elimination of methanol from the primary cycloadducts 3.After heating with an excess of nitrile oxide bis-cycloadducts 5 were also formed.Reactions
