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
描述了从海洋真菌Phoma sp。分离出的PAF拮抗剂phomactin A(1)中发现的三环呋喃喃喃单元3的简明合成。在补充研究中,探索了多种在光蛋白A中合成双环[9.3.1]十五烷环系统4的合成途径。这些研究最终合成了取代环系统79,该取代环系统包含所有的碳原子和所有必要的氧中心,以形成光蛋白A本身。
