AbstractA density functional theory study of the asymmetric transfer hydrogenation of pyruvic acid to l- and d-lactic acids catalysed by a chiral osmium complex OsH[(R,R)TsNCH(Ph)CH(Ph)NH2](eta(6)-p-cymene) reveals a formic acid assisted enantio-determining proton-coupled hydride transfer mechanism. Activation strain model analysis indicates that the C-H/pi interaction between eta(6)-arene and carboxyl ligands has a significant influence on the enantioselectivity. The replacement of p-cymene by 4-isopropyl biphenyl or phenyl is highly likely to improve the catalytic performance of the complex.
