Abstract
Nickel-catalyzed asymmetric hydrogenation of several types of alkenes proceeds in high enantioselectivity, using acetic acid or water as the hydrogen source and indium powder as electron donor. The scope of alkenes herein include α,β-unsaturated esters, nitriles,andketones as well as allylic alcohols. Asymmetric deuteration ofα,β-unsaturated estersis also achieved with deuterated water, the cheapest deuterium source.
