The [3+2]-cycloaddition of various β-substituted ethynyliodonium salts, RCCl+O−Tf, with ethyl diazoacetate, N-t-butyl-α-phenyl nitrone and t-butylnitrile oxide results in single regioisomeric pyrroles, dihydroisoxazoles, and isoxazoles respectively in moderate yields.
各种β-取代的乙炔碘铵盐RCCl + O - Tf与重氮乙酸乙酯,Nt-丁基-α-苯基硝酮和叔丁基腈的[3 + 2]-环加成反应会生成单一的区域异构吡咯,二氢异恶唑分别以中等收率生产异恶唑。
