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]pentadecaneringsystem 4 in phomactin A were explored. These studies culminated in a synthesis of the substituted ringsystem 79 containing all the carbon atoms

A total synthesis of phomactin A (1) based on a Cr(II)/Ni(II) macrocyclisation from the aldehyde vinyl iodide 11, leading to 12, followed by elaboration of the epoxyketone 16, which then undergoes spontaneous pyran-hemiacetal formation on deprotection, is described.
描述了基于醛基乙烯基碘11的Cr(II)/Ni(II)大环化合物的phomactin A (1)的完全合成,其结果是12,然后是环氧酮16的详细描述,然后在脱保护时自发形成吡喃半缩醛。
