reaction of the imine of aromatic ketones with functionalized alkenes was performed under a catalytic amount of (PPh3)3RhCl, and corresponding ortho-alkylated ketones were obtained after hydrolysis. A variety of functional groups in the alkene were tolerated in this ortho alkylation. This procedure expands the scope of ortho alkylation to the direct ortho functionalization of aromatic ketones.
[反应:见正文]在催化量的(PPh3)3RhCl下进行芳族酮亚胺与官能化烯烃的反应,水解后得到相应的邻烷基化酮。在这种邻烷基化中,烯烃中的各种官能团是可容忍的。该方法将邻烷基化的范围扩展到芳族酮的直接邻官能化。
