Rhodium-catalyzed carbonylative [2+2+1] cycloaddition reactions: catalytic formation of bicyclic cyclohexenones [corrected].

ABSTRACT

The rhodium-catalyzed carbonylative [3+2+1] cycloaddition of trienes into bicyclohexenones has been developed. The carbonylated cycloaddition products have a high regioselectivity. This catalytic system tolerates functionalities including ether, sulfonamide, and ester.
