Efficient synthetic route to ravidosamine derivatives

Concise synthesis of ravidosamine, the amino sugar constituent of ravidomycin and other antibiotics, has been achieved. The key steps include (1) regioselective reduction of benzylidene acetal with DIBAL, and (2) stereoselective reduction of oxime to the

SYNTHESIS OF METHYL 3-ACETAMIDO-3,6-DIDEOXY-L-GALACTOPYRANOSIDES AND OF METHYL 3-ACETAMIDO-3,6-DIDEOXY-L-GULOPYRANOSIDES BY REDUCTION OF 3-ULOSE O-METHYLOXIMES

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.
