  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.

  configurational 1-deoxynojirimycin isomers have been synthesized starting from a chiral cyanohydrin as the common precursor. The cyanohydrin chiral pool building block is easily accessible in large quantities by using almond hydroxynitrile lyase as the chiral catalyst in condensing hydrogen cyanide and crotonaldehyde. Our work complements the large body of literature on the synthesis of 1-deoxynojirimycin derivatives
