  名称：

  Synthesis of 1-deoxy-l-gulonojirimycin (l-guloDNJ) and 1-deoxy-d-talonojirimycin (d-taloDNJ)

  摘要：

  Carbohydrate based syntheses of azasugars with unusual configurations viz. 1,5-dideoxy-1,5-imino-L-gulitol (L-gulo DNJ) and 1,5-dideoxy-1,5-imino-L-talitol (L-talo DNJ) are reported, from D-mannose and D-fructose, respectively. The key steps in both syntheses involved reductive aminative cyclizations. Thus, L-gulo DNJ was obtained by reduction of 2,3;4,6-di-O-isopropylidene-5-O-p-toluenesulfonyl-D-mannononitrile with LiAlH4 in DME to give the protected azasugar which upon hydrolysis with HCl afforded crystalline L-guloDNJ as the HCl salt in 29% overall yield. Reduction of 6-azido-1-O-tert-butyldimethylsityl-2,3-O-isopropylidene-beta-D-ribohexulofuranose obtained from D-fructose in six steps, followed by treatment with HCl, afforded L-talo DNJ as an HCl salt in similar to10% overall yield.
