Outline of Final Research Achievements |
Based on activation of hydroxyl group which caused by chelation of diols with chiral copper catalyst,we have developed 3 methods to prepare unnatural amino acid derivatives with high optical purities: (1) Oxidative asymmetric desymmetrization of alpha-substituted serinols to prepare alpha-substituted serine derivatives, (2) Enantioselective protections for 3-hydroxyl groups of trisethanolamine in asymmetric desymmetrization manner , (3) Sulfonylative asymmetric desymmetrization of alpha-substituted serinols to prepare optically active quaternary-substituted aziridine derivatives and its application to prepare unnatural amino acid derivatives.
