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.
