Abstract

Chiral anion phase transfer enables an asymmetric Heck-Matsuda reaction of acyclic alkenyl alcohols to provide various chiral ketones in high levels of enantioselectivity. A catalytic amount of dimethyl sulfoxide (DMSO) as an additive is crucial to suppress palladium-hydride-mediated side reactions.
