, p. 913 - 928 (2007/10/02)

Both anomers of methyl 3-acetamido-3,6-dideoxy-L-galactopyranoside and of methyl 3-acetamido-3,6-dideoxy-L-gulopyranoside have been prepared by conversion of easily accessible derivatives of methyl 6-deoxy-(α and β)-L-galactopyranosides into 3-uloses and reduction of the corresponding O-methyloximes.The 1H and 13C NMR data of the four 3-acetamido methyl glucosides have been given.
