摘要：

A family of well-defined octahedral cationic chiral-atcobalt( iii ) catalysts based on ( R , R )-1,2-cyclohexanediamine and ( R , R )-1,2-diphenylethylenediamine has been examined in the dynamic kinetic resolution of an azlactone derived from N -benzoyl- tert -leucine . The reactions catalyzed by 10 mol% of Co iii complexes in the presence of 1 M aqueous NaOH solution under phase-transfer alcoholysis afforded the corresponding benzyl ester of tert -leucine with up to 76% yield and up to 66% enantioselectivity ( ee ).
