General Approach to Prostanes B<sub>1</sub>by Intermolecular Pauson-Khand Reaction: Syntheses of Methyl Esters of Prostaglandin B<sub>1</sub>and Phytoprostanes 16-B<sub>1</sub>-PhytoP and 9-L<sub>1</sub>-PhytoP
esters of Prostaglandin B1 and Phytoprostanes 16-B1-PhytoP (PPB1-I) and 9-L1-PhytoP (PPB1-II) based on the modified Julia olefination of a formylcyclopentenone and an appropriately protected hydroxy sulfone has been developed. The cyclopentenones were efficiently prepared by intermolecular Pauson–Khand reaction of a (silyloxymethyl)alkyne. The sulfone counterpart was prepared by regioselective ring-opening

invasion of the intestinal epithelium in a subject, the method comprising enterally administering to the subject a pharmaceutically effective amount of a fatty acid dissolved or suspended in a pharmaceutically acceptable carrier, wherein the fatty acid contains 10 to 30 carbon atoms, wherein the fatty acid is more particularly an unsaturated fatty acid containing 1-4 carbon-carbon double bonds and/or 1 or 2 carbon-carbon triple bonds, or the fatty acid is more particularly a cis-unsaturated fatty acid, or the fatty acid is more particularly a cis-2-unsaturated fatty acid having the formula:
wherein n is an integer of 6-26, and the fatty acid optionally includes a second carbon-carbon double bond resulting from removal of two hydrogen atoms on adjacent carbon atoms.
