  Diastereoselective Dihydroxylation and Regioselective Deoxygenation of Dihydropyranones:  A Novel Protocol for the Stereoselective Synthesis of C₁−C₈ and C₁₅−C₂₁ Subunits of (+)-Discodermolide

  摘要：

  Diastereoselective dihydroxylation of dihydropyranones and subsequent regioselective alpha-deoxygenation provides 1,3-trans-beta-hydroxy-delta-lactones stereoselectively. This protocol has been applied for the synthesis of C-1-C-8 and C-15-C-21 subunits of (+)-discodermolide.
