Ten 2,3-disubstituted 4-phenylsulfonyl isoxazolidines (3a-j) were prepared by 1,3-dipolar cycloaddition reaction of substituted nitrones (1a-j) with phenyl vinyl sulfone (2). The reaction products were identified by means of IR, NMR, and MS data. In addition, the factors influencing on the electron ionization induced mass spectral fragmentation of the title products are discussed in detail.

C,N-Diphenyl nitrones react with substituted α,β-unsaturated phenylsulfones yielding isoxazolidinic cycloadducts whose structure and stereochemistry were assigned on the basis of 1H and 13C nmr data.The cycloaddition regioselectivity is discussed in accor
