Owing to high atom economy, chemoselectivity, and stereoselectivity, the transition-metal- catalyzed asymmetric hydrogenation of C= C bonds has become one of the most reliable methods for the preparation of optically active compounds both in academia and in industry.[1] In the asymmetric hydrogenation of a double bond, chiral induction arises from catalyst differentiation of the prochiral faces of the bond. The Re and Si faces are much ...
