  Synthesis of Key Fragments of Leiodelide A

  摘要：

  The synthesis of all key fragments of the marine macrolide lelodelide A is described. The polyoxygenated northern subunit is derived from D-xylose, while the southern subunit is rapidly assembled via an aldol reaction and Horner-Wadsworth-Emmons olefination. This highly convergent approach will allow for rapid modification and assembly of several isomers of lelodelide A, which may be necessary considering the assignment of leiodelide B has been previously shown to be incorrect.
