Palladium-catalyzed direct acylation of ketoximes and aldoximes from the alcohol oxidation level through C-H bond activation

A highly efficient palladium-catalyzed oxidative ortho-acylation of O-methyl ketoximes and O-methyl aldoximes with benzylic and aliphatic alcohols from the alcohol oxidation level is described. This protocol potentially provides new opportunities to use readily available alcohols as starting materials for catalytic reactions, and represents a catalytic alternative to transcend the barriers imposed by classical Friedel-Crafts acylation.
