  Oxocarbenium Ion Cyclizations for C-Branched Cyclitols:  Synthesis of a Relay Intermediate for Fumagillin Analogues

  摘要：

  [GRAPHICS]A highly stereoselective oxocarbenium ion-alkene cyclization for synthesis of C-branched cylitols is described. This methodology was applied to 10S, a potentially versatile intermediate for side-chain analogues of the antiangiogenic agent fumagillin. Compound 105 was subsequently converted to diene 5. Because racemic 5 has been converted to racemic fumagillin, this synthesis of 5 constitutes a formal synthesis of the natural product.
