Abstract A series of 4-hydroxyl-Δ 2 -isoxazol-6(6a H )-one derivatives was prepared by magnesium ion-mediated diastereoface-selective 1,3-dipolar cycloaddition of aromatic nitrile oxides with pyrrolidinone derivatives. The reaction of 4-hydroxyl-Δ 2 -isoxazol-6(6a H )-one derivatives with dimethylsulfoxide and oxalyl chloride under Swern conditions led to a Δ 2 -isoxazole-4,6(5 H ,6a H )-dione.
