  One of the hydroxyl groups in glycosides was regio- and stereo-selectively converted to an amino group as follows. A glycoside was regioselectively converted to an oxo-glycoside by bis-tributyltin oxide-bromine oxidation. Oximation of this and reduction of the resulting oxime in a stereoselective manner gave an amino-glycoside in a satisfactory yield.By application of this method, 4-amino-4-deoxy-D-galactose, 4-amino-4-deoxy-L-arabinose, 3-amino-3-deoxy-D-allose, 3-amino-3-deoxy-D-glucose, 3-amino-3-deoxy-D-ribose, 3-amino-3-deoxy-D-xylose, and 2-amino-2-deoxy-D-mannose were synthesized in satisfactory yields from D-xylose or D-glucose as their α- or β-methyl glycosides. The method also provided a practical synthetic route to nojirimycin (5-amino-5-deoxy-D-glucose), a glucosidase-inhibitory antibiotic, from D-glucose.

• Stereoselective synthesis of methyl 4,6-O-benzylidene-2-C-methoxycarbonylmethyl-α-d-ribo-hexopyranosid-3-ulose, and its X-ray crystallographic analysis

  Methyl 4,6-O-benzylidene-2-C-methoxycarbonylmethyl-alpha -D-ribo-hexopyranosid-3-ulose has been stereoselectively synthesized in 65% yield by reaction of methyl 4,6-O-benzylidene-alpha -D-arabino-hexopyranosid-2-ulose with diethyl malonate. X-ray crystallographic structure analysis reveals that the chain-branch and the OH group are bonded to C-2 in axial and equatorial positions, respectively. The molecules in the crystal lattice are stacked along a one-dimensional chain, with intermolecular hydrogen bonds between O-8 of one molecule and 2-OH of the next as well as intramolecular hydrogen bonds between O-3 and 2-OH. All phenyl groups are parallel as well as the planes of sugar rings in the molecular columnar stacking. (C) 2001 Elsevier Science Ltd. All rights reserved.
