Novel phosphoramidate prodrugs of N-acetyl-(d)-glucosamine with antidegenerative activity on bovine and human cartilage explants

(d)-Glucosamine and other nutritional supplements have emerged as safe alternative therapies for osteoarthritis (OA), a chronic and degenerative articular joint disease. In our preceding paper, a series of novel O-6 phosphate N-acetyl (d)-glucosamine prod

Synthesis of 1,2-cis- and 1,2-trans-glycosides of 2-acetamido-4,6-O- benzylidene-2-deoxy-d-glucopyranose by anomeric O-alkylation

The reaction of a partially protected 1-hydroxy derivative of N-acetyl-d-glucosamine with benzyl bromide under conditions of anomeric O-alkylation was studied. It was found that the stereoselectivity of the reaction depended on the nature of the alkali me

Substrate specificity of N-acetylhexosamine kinase towards N-acetylgalactosamine derivatives

We report herein a bacterial N-acetylhexosamine kinase, NahK, with broad substrate specificity towards structurally modified GalNAc analogues, and the production of a GalNAc-1-phosphate library using this kinase.

Synthesis and biological evaluation of a lipid A derivative that contains an aminogluconate moiety

A highly convergent strategy for the synthesis of several derivatives of the lipid A of Rhizobium sin-1 has been developed. The synthetic derivatives are 2-aminogluconate 3 and 2-aminogluconolactone 4, both of which lack C-3 acylation. These derivatives w

Palladium-catalysed asymmetric allylic alkylation using new chiral phosphinite-nitrogen ligands derived from D-glucosamine

Novel phosphinite-nitrogen chiral ligands synthesized from D-glucosamine furnish a high level of enantiomeric excess (up to 96% ee] in palladium-catalysed allylic alkylation.

Palladium-catalyzed asymmetric allylic substitution reactions using new chiral phosphinite-oxazoline ligands derived from D-glucosamine

Novel 2-alkyl- or 2-aryl-4,5-(4,6-O-benzylidene-3-O-(diphenylphosphino)- 1,2-dideoxy-α-D-glucopyrano)-[2,1-d]-2-oxazolines (5a-f) have been prepared from D-glucosamine hydrochloride. They work effectively as chiral ligands and provide a high level of enantiomeric excess in palladium-catalyzed allylic alkylation and amination reactions. The allylic alkylation of 1,3-diphenyl-3- acetoxyprop-1-ene with dimethyl malonate proceeds smoothly in the presence of 0.25 mol % [Pd(η3C3H5)Cl]2 and the chiral ligand 5a having the smallest substituent on oxazoline at 0 °C within 6 h to furnish the highest enantiomeric excess (96% ee). The ligand 5a is also effective for the Pd- catalyzed amination of ethyl 1,3-diphenylprop-2-enyl carbonate, leading to the corresponding allylic amine in 94% ee. The full scope and limitations using ligands 5a-f in the allylic substitution reactions are described.
