Diastereomeric 4-aryl-3-epoxypropionyl-2-pyrazolines were obtained by cycloaddition of diazomethane to β-arylacrylyloxiranes.It was established that, in addition to the formation of pyrazolines, competitive addition of diazomethane to the carbonyl group to give oxadiazolines occurs when electron-donor substituents are present in the aromatic ring in the 2 or 4 position.Some chemical properties of 4-aryl-3-epoxypropionyl-2-pyrazolines were studied.
