Fluoroprostaglandins: Synthesis and Biological Evaluation of the Methyl Esters of (+)-12-Fluoro-, (-)-ent-12-Fluoro-, (+)-15-epi-Fluoro-, and (-)-ent-15-epi-12-Fluoroprostaglandin F2α

The synthesis and biological activity of the methyl esters of (+)-12-fluoroPGF2α, (+)-15-epi-12-fluoroPGF2α, (-)-ent-12-fluoroPGF2α, and (-)-15-epi-12-fluoroPGF2α are described.Each fluoroprostaglandin has been evaluated from pregnancy interruption in the hamster and smooth-muscle stimulating effects on gerbil colon and hamster uterine strips.All fluoroprostaglandins synthesized were shown to be neither substrates for 15-hydroxyprostaglandin dehydrogenase nor inhibitors of the enzyme.

The optically pure sodium alcoholate dextrorotary chlorine forefront of the method for the preparation of

The invention relates to a preparation method of optically pure dextro cloprostenol sodium. The method comprises the following steps: using the combination of ketonic acid and S-phenylethylamine resolving agent, and carrying out chiral resolution to obtain S-propenylphosphonate with the structural formula of R-ketonic acid; then separating to obtain R-chlorone and preparing to obtain R-cloprostenol sodium. The preparation method has the benefits that the optically pure dextro cloprostenol sodium in the invention is called D-cloprostenol sodium for short, the using amount only needs one third of cloprostenol sodium being a racemic modification in current market, and the pesticide effect is obviously better than cloprostenol sodium with three times of using amount.

ABSOLUTE CONFIGURATION OF (1R,2S,4R,6S,7R)-(+)-3-OXOTRICYCLO2,6>HEPTANE-7-CARBOXYLIC ACID

The title acid was assigned absolute configuration on the basis of stereoselective condensation with optically active amines.
