标题:Process for stereoselective synthesis of prostacyclin derivatives
发明人：MORIARTY ROBERT M; PENMASTA RAJU; GUO LIANG; RAO MUNAGALA S; STASZEWSKI JAMES P
权利人:UNITED THERAPEUTIC CORP
摘要:An improved method is described for making 9-deoxy-PGF 1 -type compounds. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds. The invention also relates to novel intermediates prepared during the synthesis of the 9-deoxy-PGF 1 -type compounds.
