✦ Synopsis

Palladium(lI)-catalyzed aerobic oxidation of conjugated dienes 3 having a stabilized carbon nucleophile in the side chain resulted in a carbecyclization with an overall 1,4-cis-addition to the diene. The reactions were carried under an atmosphere of molecular oxygen in DMSO. An interesting exolendo selectivity of the electronwithdrawing groups in the tether led to a control of the relative stereochemistry between four stereogenic centers.
