  Unexpected reductions of glycosyl spacer-armed phthalimides

  摘要：

  An unusual reductive ring-opening reaction in the title compounds, of the phthalimide group with sodium hydride in anhydrous DMF is observed for the first time and the presumed mechanism is described in detail, An unexpected hydrogenation of the phthalimide group was also observed.
