Description
Summary:Various [gamma]-benzyloxy vinylogous urethanes underwent [1,2]-Wittig rearrangement, followed by lactonization to provide [gamma]-benzyl vinylogous urethane lactones. Applications of the resulting [gamma]-benzyl butenolides were concisely demonstrated in the formal synthesis of maculalactone A, the synthesis of the BCD ring of planchol C, and the total synthesis of [gamma]-lycorane.
