  Catalytic asymmetric hydroxylation of α-alkoxycarbonyl amides with a Pr(OiPr)3/amide-based ligand catalyst

  摘要：

  A catalytic asymmetric hydroxylation of N-nonsubstituted alpha-alkoxycarbonyl amides is described. A new effective catalyst comprising Pr((OPr)-Pr-i)(3) and a fluoro-substituted amide-based ligand was identified using oxaziridine as the oxidizing reagent. The catalyst components were in dynamic equilibrium in the reaction mixture, which assembled to form the associated transition state through metal coordination and hydrogen bonding.
