  A pH Study on the Chiral Ketone Catalyzed Asymmetric Epoxidation of Hydroxyalkenes

  摘要：

  A detailed study shows that the chiral ketone catalyzed asymmetric epoxidations of hydroxyalkenes are highly pH dependent. The lower enantioselectivity obtained at low pH is attributed to the substantial contribution of the direct epoxidation by Oxone. At high pH the epoxidation mediated by chiral ketone out-competes the racemic epoxidation, leading to higher enantioselectivity. The effective substrates include allylic alcohol, homoallylic alcohol, and bishomoallylic alcohol. In most cases, over 90% ee was obtained.

  A new approach to the synthesis of N-methyl-γ-amino-β-hydroxy acids, compounds that are essential components of several depsipeptides exhibiting highly interesting therapeutic profiles, is presented. Relevant steps in the synthetic sequence involve the totally stereoselective preparation of a protected aminoalkyl epoxide from a highly enantiopure 2,3-epoxy alcohol, efficient N-methylation and three-step
