| Abstract: | Initial examples of a Rh(I)-catalyzed 2+2+1] reaction of diene-enes and CO are described. This method allows for the facile, efficient, and diastereoselective construction of a variety of alkenyl cyclopentanones in good to excellent yields. Control studies show that the diene moiety is required for this process as bis-enes do not give the 2+2+1] products under the same conditions. |
