Highly Efficient and Highly Enantioselective Asymmetric Hydrogenation of Ketones with TunesPhos/1,2-Diamine−Ruthenium(II) Complexes

This is the authors' abstract. We don't add key points for this paper.

The TunePhos/diamine-Ru(II) complex combined with t-BuOK in 2-propanol effectively catalyzes enantioselective hydrogenation of a wide range of simple ketones including aromatic, heteroaromatic, alpha,beta-unsaturated, and cyclopropyl ketones, affording high reactivity (up to 1,000,000 TON) and excellent enantioselectivities (>99% ee for 13 examples).
