摘要：
Recent advances in (CpMIII)-M-x catalysis (M=Co, Rh, Ir) have enabled a variety of enantioselective C(sp(2))-H functionalization reactions, but enantioselective C(sp(3))-H functionalization is still largely unexplored. We describe an asymmetric C(sp(3))-H amidation of thioamides using an achiral Co-III/chiral carboxylic acid hybrid catalytic system, which provides easy and straightforward access to chiral beta-amino thiocarbonyl and beta-amino carbonyl building blocks with a quaternary carbon stereocenter.
