New α-chloralose derivatives

Chloralose is an easily available carbohydrate derivative bearing biological properties. It constitutes a convenient starting material for various synthetic developments. Herein we describe the preparation of hydroxylamino derivatives of α-chloralose using well-established synthetic procedures

Hydroxyamino Sugar Derivatives: New Glycolipid Analogs

Synthetic glycolipid analogs are very useful as nonionic detergents for solubilization of membrane proteins [1]. Although a large number of such detergents were described, very few ones fully satisfy the desirable properties needed for such compounds [2].</p

Spin labeled hydroxyproline analogues

Abstract The synthesis and properties of both epimers of 4-(N-hydroxyamino)-N-tosyl-L-proline methyl ester and derivatives thereof are reported. In the presence of air, the compounds bearing a free N-hydroxyamino group oxidized in solution to give the corresponding aminoxyl free radicals, EPR spectra of which were recorded. None of these compounds showed any interesting biological activity as such, but they constitute potential synthetic building blocks towards spin labeled glycopeptide or oligopeptide analogues
