  摘要：

  Methyl 3-azido-2,3-dideoxy-alpha/beta-D-arabino- and -alpha/beta-D-ribo-hexopyranosides were transformed into 6-iodo analogues via p-tolylsulfonyl compounds. Elimination of hydrogen iodide from 6-iodo glycosides provided methyl 4-O-acetyl-3-azido-2,3,6-trideoxy-alpha- and -beta-D-threo-hex-5-eno-pyranosides or 3-azido-4-O-p-tolylsulfonyl-2,3,6-trideoxy-alpha-D-threo- and -beta-D-erythro-hex-5-eno-pyranosides. Ferrier's carbocyclization of 4-O-acetyl-3-azido-2,3,6-trideoxy-alpha- and -beta-D-threo-hex-5-eno-pyranosides gave (2S,3R,5R)-2-acetoxy-3-azido-5-hydroxycyclohcxanone, which was converted into oxime. The 2-OAc group in oxime was substituted by azide ion to yield (2R,3R,5R)-2,3-diazido-5-hydroxycyclohexanone oxime. The configuration and conformation of all products are widely discussed on the basis of the H-1 and C-13 NMR.
