  Photochemical Transformation of Levoglucosan Imides to Anhydrosugar-Annelated Azepanediones and Azocanediones

  摘要：

  By reaction of O-protected 3-amino-1,6-anhydro-beta-D-glucopyranose with succinic, glutaric, and tartaric anhydride, respectively, the corresponding 3-substituted succinimido, glutarimido, and tatarimido derivatives were obtained. Irradiation of the succinimido and glutarimido derivatives at 254 nm gave 1,4-diradical intermediates by gamma-hydrogen abstraction (Norrish Type 11 reaction) which subsequently recombined (Yang cyclization) to form azetidinols. These in turn fragmented and led to azepanedione and azocanedione derivatives. In contrast, irradiation of the tartarimido derivative resulted in elimination and led to both isomeric enolethers.
