Reaction Steps

To 1.1 g of platinium in 50 ml of ethyl acetate was added a solution of 11 g (0.028 mol) of [3aR-[3a alpha,4alpha(1E,3R*,4S*),5beta,6a alpha]]-5-(benzoyloxy)-4-(4-fluoro-3-hydroxy-1-octenyl)hexahydro-2H-cyclopenta[b]furan-2-one in 110 ml of ethyl acetate. The mixture was then hydrogenated until the theoretical uptake of hydrogen was complete and then filtered through a bed of Celite. The solvent was then removed under reduced pressure and the residue chromatographed over 250 g of silica gel (toluene --α 30% by volume ethyl acetate/70% by volume toluene) to afford 10.7 g of [3aR-[3a alpha,4alpha(3R*,4S*),5beta,6a alpha)]-5-(benzoyloxy)-4-(4-fluoro-3-hydroxyoctyl)hexahydro-2H-cyclopenta[b]furan-2-one (94% yield) as a colorless oil.
