Palladium(II)-catalyzed aerobic oxidation of conjugateddienes 3 having a stabilized carbon nucleophile in the side chain resulted in a carbocyclization with an overall 1,4-cis-addition to the diene. The reactions were carried under an atmosphere of molecular oxygen in DMSO. An interesting selectivity of the electron-withdrawing groups in the tether led to a control of the relative stereochemistry
