A highly efficient asymmetric hydrogenation of α,β-unsaturated carboxylic acids with tetrasubstituted olefin catalyzed by chiral spiro iridium complexes has been developed for the preparation of chiral α-substituted carboxylic acids in excellent enantioselectivities (up to 99% ee).
已经开发出由手性螺铱配合物催化的具有四取代烯烃的α,β-不饱和羧酸的高效不对称加氢,用于制备具有优异对映选择性(至多99%ee)的手性α-取代的羧酸。
