Heparansulfateanalogues: Highly efficient one‐pot multienzyme (OPME) chemoenzymatic systems for the activation and transfer of N‐acetylglucosamine (GlcNAc) and glucuronic acid (GlcA) have been developed. They were applied to the sequentialtailoredsynthesis of N‐sulfatedanalogues of heparansulfateoligosaccharides, which could be potential therapeutics.

An operationally simple protocol for diazotransfer on amine-containing carbohydrates has been developed. This high-yielding reaction can be conducted under ambient conditions. Reaction completion is indicated by the colour change of the Cu(II) catalyst. The utility of this protocol in chemical glycosylation has been demonstrated through the preparation of azide-containing glycosyl donors with orthogonal

Novel bola-amphiphilic compounds have been synthesised with D-glucose or D-galactose moieties as polar head groups. The sugar groups are coupled to the hydrophobic bridge, a chain of ten or twelve methylene groups, by an amide function at the C-2 site (2-alkylamido-2-deoxy-D-glucose derivative) or a glycuronamido function at the C-6 site. The former series is glycosylated with a cinnamyl group and the latter with octyl or decyl groups to afford pseudo macrocyclic compounds. (C) 1997 Elsevier Science Ltd.
