report non-decarbonylative Mizoroki–Heck reactions of amide derivatives. The transformation relies on the use of nickel catalysis and proceeds using sterically hindered tri- and tetrasubstituted olefins to give products containing quaternary centers. The resulting polycyclic or spirocyclic products can be obtained in good yields. Moreover, a diastereoselective variant of this method gives access to an
我们报告了酰胺衍生物的非脱羰基Mizoroki-Heck反应。该转化依赖于镍催化的使用,并使用空间受阻的三和四取代的烯烃进行,以得到含有季中心的产物。可以高收率获得所得的多环或螺环产物。而且,该方法的非对映选择性变体使得能够接近带有邻近的,高度取代的sp 3立体中心的加合物。这些结果表明,酰胺衍生物可以用作组装复杂支架的基础。
