N-Substituted α-amino esters are widely used as chiral intermediates in a range of pharmaceuticals. Here we report the enantioselective biocatalyic synthesis of N-substituted α-amino esters through the direct reductive coupling of α-ketoesters and amines employing sequence diverse metagenomic imine reductases (IREDs). Both enantiomers of N-substituted α-amino esters were obtained with high conversion and excellent enantioselectivity under mild reaction conditions. In addition >20 different preparative scale transformations were performed highlighting the scalability of this system.

A copper(I)-catalyzed addition of alkylborane reagents to α-iminoacetates has been developed to assemble both acyclic and cyclic α-branched α-amino carboxylic acid derivatives in good yields. A wide variety of unactivated alkenes are well tolerated in this transformation. (Figure presented.).
