Synthesis of dimeric carbacyclin structures: Iloprost-11-iloprost-ester and iloprost-15-iloprostester

Jürgen Westermann; Michael Harre; Helmut Dahl

Abstract The syntheses of dimeric carbacyclins 3 and 4 were accomplished by coupling of suitably protected precursors with DCCI in the presence of DMAP starting from the carbacyclin iloprost.
