Abstract
A cooperative primary amine and ketone dual catalytic approach enables the asymmetric α-hydroxylation of β-ketocarbonyls with H2O2 in excellent yield and enantioselectivity. Notably, late-stage hydroxylation for peptidyl amide or chiral esters can also be achieved with high stereoselectivity.
