  A General Synthesis of Iminosugars

  摘要：

  1-Deoxynojirimycin, 1-deoxymannojirimycin, and 1-deoxygalactostatin have been synthesized by epoxidation of tri-O-acetyl-6-deoxyhex-5-enopyranosyI azides followed by methanolysis, deacetylation, and catalytic hydrogenation. 1,6-Dideoxygalactostatin was obtained by the reaction of 2,3,4-tri-O-acetyl-6-deoxy-beta-L-arabino-hex-5-enopyranosyl azide with NIS in methanol followed by deacetylation and catalytic hydrogenation. The overall yields were 4.4-23.5% over seven to nine steps.
