| Abstract: | 6-acetamido-6,8-dideox-1,2:3,4-di-O-isopropylidene- D -glycero-α-D-galacto-octopyranos-7-ulose (6), has been synthesised from D -galactose. The side chain elongation was carried out by cyano-amination of the protected dialdo sugar (2), followed by N-acetylation, and a subsequent Grignard reaction. |
