Non-canonical amino acids are important building blocks in the synthesis of natural products, peptides and drugs. Now, a one-pot chemoenzymatic approach to synthesize branched azacyclic non-canonical amino acids is reported. This method combines enzymatic transamination of 2,n-diketoacids and stereocontrolled chemical reduction to provide the desired products with high stereoselectivity.
