Palladium(II)-catalyzed 1,4-oxidation of conjugateddienes involving a carbocyclization has been developed. Chloropalladation of the triple bond in a dienyne and subsequent addition of the vinylpalladium to the conjugateddiene creates a (π-allyl)palladium intermediate, which undergoes a quinone-induced chloride attack to give the product. The overall 1,4-addition of the vinylic carbon and the chloro
