ABSTRACT:
The present specification provides novel analogs of carbacyclin (CBA.sub.2), 6a-carba-prostacyclin (6a-carba-PGI.sub.2), which have pronounced prostacyclin-like pharmacological activity, e.g., as platelet antiaggregatory agents. Specifically the novel chemical analogs of CBA.sub.2 are those substituted by fluoro (C-5), alkyl (C-9), interphenylene (C-5), and methano (C-6a,9). Further provided are benzindene analogs of CBA.sub.2 and substituted forms thereof, i.e., 9-deoxy-2',9-methano (or 2',9-metheno)-3-oxa-4,5,6-trinor-3,7-(1',3'-interphenylene)-PGF.sub.1 compounds. Also provided are a variety of novel chemical intermediates, e.g., substituted bicyclo[3.3.0]octane intermediates, and chemical process utilizing such intermediates which are useful in the preparation of the novel CBA.sub.2 analogs.
