An enantioselective synthesis of E/Z-13, 14-dinor-inter-p-phenylene carbacyclin (E/Z-2d) by a new strategy has been realized that holds the prospect of serving as a general route for carba-prostacyclin analogues. The key intermediate in this synthesis is the bicyclic azoene Ts-9, and the key step is the regio-and stereoselective conjugate addition of the chiral arylcopper compound Cu-8d/Pn-Bu3 to the azoene with formation of hydrazone 7d. ...
