  Palladium(II)-Catalyzed Cyclization of Urethanes and Total Synthesis of 1-Deoxymannojirimycin

  摘要：

  [GRAPHICS]The palladium(II)-catalyzed cyclization of the urethane 8, which was derived from D-mannitol, gave the cyclic compound 9 with excellent diastereoselectivity. During these transformations, the Pd(II) species are not reduced and thus the catalyst can recycle without its reoxidation, The cycloadduct 9 was converted to 1-deoxymannojirimycin.
