Punaglandin 4 (208) is an example of a C-10 chlorinated prostanoid isolated from the Hawaiian octocoral telesto riisei. Its potent antitumor activity has attracted considerable synthetic interest. Characteristic of the a-chain is the same familiar dihydroxy stereochemistry found in (7, 7 )-tartaric acid. Wittig reaction of 167 with the phosphorane of [2-(l,3-dioxan-2-yl)ethyl]triphenylphosphonium bromide (205) followed by catalytic reduction and simultaneous debenzylation affords a primary alcohol, which is converted to aldehyde 206 in two oxidative steps. Aldol coupling of 206 with racemic cyclopentenone 207 (R=MOM) provides a statistical mixture of all four possible diastereomers. After chromatographic purification and protective group transformations, the target molecule 208 is obtained in 30—40% yield. The remaining three aldol products have been similarly converted to the diastereomers of 208 [75] (Scheme 47). [Pg.346]
