| Abstract: | The synthetic route for the construction of the 6-8-5 tricyclic carbon frameworks has been developed. The RhCl(CO)dppp]2-catalyzed intramolecular Pauson–Khand-type reaction of the bis(allene)s, derived from dimedone, provided the corresponding bicyclo6.3.0] skeleton in one operation. |
