Recent Applications of Carbon‐Nitrogen Lyases in Asymmetric Synthesis of Noncanonical Amino Acids and Heterocyclic Compounds

Carbon-nitrogen (C−N) lyases are enzymes that normally catalyze the cleavage of C−N bonds. Reversing this reaction towards carbon-nitrogen bond formation can be a powerful approach to prepare valuable compounds that could find applications in everyday life. This review focuses on recent (last five years) applications of native and engineered C−N lyases, either as stand-alone biocatalysts or as part of multienzymatic and chemoenzymatic cascades, in enantioselective synthesis of noncanonical amino acids and dinitrogen-fused heterocycles, which are useful tools for neurobiological research and important synthetic precursors to pharmaceuticals and food additives.
