Recent progress in medicinal chemistry has resulted in the frequent use of non-natural amino acids as intermediates for drug substances. Typically, they have derived from natural amino acids, thus showing structure similar but different from natural L-amino acids. While amino acids containing aromatic groups can be produced effectively and relatively easily by asymmetric catalysis, new aliphatic amino acids often require a specific methodology. Here we would like to discuss our approach to several non-natural aliphatic α-amino acid examples by selecting the optimum synthetic technology including asymmetric induction, chiral pool, and dynamic resolution. We would also like to present the integration of our noted expertise in biotechnology with synthetic technology in an effort to produce these key pharmaceutical intermediates.
