Enantioselective Pd(II)-Catalyzed Intramolecular Oxidative 6- endo Aminoacetoxylation of Unactivated Alkenes

J Am Chem Soc. 2018 Jun 20;140(24):7415-7419. doi: 10.1021/jacs.8b03767. Epub 2018 Jun 8.

Abstract

A novel asymmetric 6-endo aminoacetoxylation of unactivated alkenes by palladium catalysis, which yields chiral β-acetoxylated piperidines with excellent chemo-, regio- and enantioselectivities under very mild reaction conditions, has been established herein by employing a new designed pyridine-oxazoline (Pyox) ligand. Importantly, introducing a sterically bulky group into the C-6 position of Pyox is crucial to enhance the reactivity of the aminoacetoxylation of alkenes.
