Stable nitrile oxides are added stereospecifically and regioselectively to the carbon-carbon double bond of 2-phenyl-4-arylidene-5(4H)-oxazolones resulting spiro-derivatives 3, 5.The spectral properties of the reaction products are discussed.The cycloadducts give several substituted isoxazolines via an opening of the oxazolone ring with nucleophilic reagents.
