The synthesis of benzindene prostacyclin analogs as potential antiulcer agents

Two new diastereomeric benzindene prostacyclin analogs (U-72,382 and U-72,383) related to the potent antiulcer agent U-68,215 have been synthesized. These cyclohexyl ring modified analogs of U-68,215 were prepared to determine how the gastrointestinal and hypotensive endpoints observed for U-68,215 would be affected.
