Abstract

The [RhCl(CO)2]2-catalyzed [2+2+1] cycloaddition of bis(allene)s, which have a substituent at the allenic terminus, produced the 8-substituted bicyclo[5.3.0]deca-1(10),6-dien-9-one frameworks. The synthesis of 8,10-dimethylbicyclo[5.3.0]deca-1(10),6-dien-9-one could also be achieved from the bis(1,1,3-trisubstituted-allene).
