Directed Evolution of Nonheme Fe Enzymes for Enantioselective and Regiodivergent 1,3- and 1,4-Nitrogen Migration: Biocatalytic Asymmetric Synthesis of Noncanonical α- and β-Amino Acids.
Biocatalyst-controlled regioselective C(sp)-H functionalization of carboxylic acid derivatives provides a powerful method for the synthesis of noncanonical α- and β-amino acids. Herein, we report a nonheme Fe enzyme-catalyzed, regiodivergent, and enantioselective nitrogen migration, enabled by directed evolution of 1-a...
