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.
本规范提供了新型的
卡巴环素(C
BA.sub.2)、6a-卡巴-
前列环素(6a-car
BA-
PGI.sub.2)的类似物,这些类似物具有明显的
前列环素类药理活性,例如作为血小板抗凝剂。具体而言,C
BA.sub.2的新型
化学类似物是那些被
氟(C-5)、烷基(C-9)、互
芳烃(C-5)和
甲基(C-6a,9)取代的物质。此外,还提供了C
BA.sub.2的
苯并二
烯类似物及其取代形式,即9-去
氧-2',9-
甲基(或2',9-甲
烯)-3-
氧杂-4,5,6-三
脱-3,7-(1',3'-互芳基)-
PGF.sub.1化合物。还提供了各种新型的
化学中间体,例如取代的双环[3.3.0]
辛烷中间体,以及利用这些
中间体的
化学过程,这些
中间体在新型C
BA.sub.2类似物的制备中非常有用。
