A very effective spirocyclization procedure for installing nucleophiles (Nu = N3, NO2, SCN, SO2Tol, and halogens) viaiodonium(III) salts has been developed using the combination of iodoarene and mCPBA. The high-yielding syntheses of the cyclohexadienone-type spirocyclic compounds 2 having varied functionalities in the skeletons have been achieved from the aryl alkynes 1 with the optimized bis(iodoarene) 3h.
使用碘芳烃和 mCPBA 的组合,开发了一种非常有效的螺环化方法,用于安装亲核试剂(Nu = N3、NO2、SCN、SO2Tol 和卤素)经由碘鎓 (III) 盐。以芳基炔烃1和优化的双(碘芳烃)3h为原料,高产率合成了骨架中具有不同官能度的环己二烯酮型螺环化合物2。
