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
