Palladium-catalyzed intramolecular aminoacetoxylation of unactivated alkenes with hydrogen peroxide as oxidant.

A palladium-catalyzed intramolecular aminoacetoxylation of unactivated alkenes was developed in which H2O2 was used as the sole oxidant. A variety of 3-acetoxylated piperidines were obtained in good yields with good to excellent regio- and diastereoselectivities. Mechanistic study revealed that the addition of di(2-pyridyl) ketone (dpk) ligand was crucial to promote the oxidative cleavage of the C-Pd(II) bond by H2O2 to give the C-OAc bond.
