  Synthesis of macrotetrolide α, a designed polynactin analog composed of bishomononactic acids

  摘要：

  Macrotetrolide alpha (1), a designed polynactin analog composed of (+)- and (-)-bishomononactic acids, was synthesized. The monomeric acids were prepared using cis-selective iodoetherification and optical resolution of the corresponding O-acetylmandelates as the key steps. Esterification and macrolactonization of the monomers were performed by Corey-Mukaiyama-Gerlach method. Compound 1 showed no immunosuppressive activity contrary to other natural polynactin congeners.

  Macrotetrolide alpha, a designed analog of polynactin composed of (+)- and (-)-bishomononactic acids, was synthesized. These monomers were prepared via optical resolution of the corresponding (S)-O-acetylmandelates. Assembly of the monomers to macrotetrolide alpha took seven steps without any loss of the intermediates.
