(+)-12-Fluoro-13,14-dihydroprostaglandin F2alpha methyl ester (2a) and (+)-15-epi-12-fluoro-13,14-dihydroprostaglandin F2alpha methyl ester (2b) were prepared from the readily available (-)-7-fluorospiro[bicyclo[2.2.1]hept-5-ene-2,2'-[1,3]dioxolane]-7-methanol (3). Fluoroprostaglandins 2a and 2b possess truly significant separations of antifertility activity from smooth-muscle stimulating properties. In addition, our studies showed that 2a and 2b were totally inert toward the placental 15-hydroxyprostaglandin dehydrogenase.
