  Synthesis of stereodefined Z-vinyl iodides from carbohydrates as a prelude to C/D ring assembly in taxanes

  摘要：

  D-Mannitol has been transformed into 10 and 14, while D-glucose has served as precursor to 20. In the latter example, key steps include stereocontrolled vinylation, oxidative fragmentation of the tetrahydrofuran-2,3-diol, oxetane ring closure, and highly stereoselective iodoolefination.
