摘要：

A series of novel pyrazolyl isoxazolines were synthesized by 1,3-dipolar cycloaddition of pyrazolyl nitrile oxide with various activated alkene, such as acrylonitrile, methyl acrylate, and vinyl acetate, in the presence of iodobenzene diacetate in methanol containing a catalytic amount of TFA at room temperature (13 compounds upto 92% yield were isolated).
