A series of 9-halo PGF analogues 1-2 and 5-13 were synthesized and biologically evaluated. Among the compounds, 2 was the best EP2-receptor agonist. A practical method of synthesizing 2 via the Julia olefination of an aldehyde 3 with an optically active sulfone 4, which was prepared by Sharpless asymmetric epoxidation of 15, was developed. Other 9-halogenated PGF analogues were synthesized essentially by the same procedure and evaluated. The absolute configuration of 16-OH of 2 was determined as S by the X-ray analysis of a salt consisting of a 1/1 molar ratio of 2 and L-lysine.
