  Efficient Assembly of the Phomactin Core via Two Different Macrocyclization Protocols

  摘要：

  [GRAPHICS]The core structure of phomactins C and D was assembled by an efficient strategy starting from 3,4-dimethylcyclohexen-2-one. Key reactions include (1) a high yielding and highly diastereoselective Michael addition of a mixed cuprate, (2) a carbonylative alkyne-enoltriflate coupling or an intramolecular addition of an acetylide onto an aldehyde to form the macrocycle, (3) chemoselective Michael addition of a cuprate to an enynone, to give the carbon framework of desformyl phomactin C or D, and finally (4) regioselective addition of a thia-nucleophile to the more reactive beta -position of the resulting dienone.

  A concise synthesis of the tricyclic furanochroman unit 3 found in the PAF antagonist phomactin A (1) isolated from the marine fungus Phoma sp., is described. In complementary studies, a variety of synthetic routes towards the bicyclo[9.3.1]pentadecane ring system 4 in phomactin A were explored. These studies culminated in a synthesis of the substituted ring system 79 containing all the carbon atoms

  Treatment of the aldehyde vinyl iodides 17, 19 a and 19 b in DMSO with CrCl2-NiCl2 resulted in their macrocyclisation to the oxygenated ring systems 18, 20, and 21 respectively (43-63%) of the PAF antagonist phomactin A isolated from the marine fungus Phoma sp. The same bicyclo[9.3.1]pentadecane ring system 24 could also be produced by treatment of the polyene 23 with Grubbs' ruthenium catalyst in hot CH2Cl2 for 10 h (∼ 30%).

  用 CrCl2-NiCl2 在二甲基亚砜中处理醛乙烯基碘化物 17、19 a 和 19 b，可使它们大环化，分别生成从海洋真菌 Phoma sp.中分离出来的 PAF 拮抗剂 phomactin A 的含氧环系统 18、20 和 21（43-63%）。同样的双环[9.3.1]十五烷环系统 24 也可以通过在热 CH2Cl2 中用 Grubbs 的钌催化剂处理聚烯 23 10 小时而生成（30%∼）。
