cross-dehydrogenative coupling reaction between α-hydroxy ketones and N-arylglycine derivatives for the synthesis of various β-hydroxy-α-amino acidderivatives is disclosed. The compatibility of substrate and oxidant in this reaction is achieved by controlling the dosing sequence, and the products are successfully obtained in 29–93% yields. This work provides a new method for the synthesis of β-hydroxy-α-amino

An enantioselective four-componentreaction of a diazoketone, water, an aniline and ethyl glyoxylate in the presence of catalytic Rh2(OAc)4 and a chiral Bronsted acid was developed to efficiently produce beta-hydroxy-alpha-amino acid derivatives in good yields with high diastereoselectivity and enantioselectivity.
