Abstract

Stereoselective synthesis of a- and b-linked glucopyranosylamide derivatives via the in situ generation of glucosyl isoxazolines has been performed utilizing a modified Staudinger methodology. Glucopyranosylamides were derivatized with thiol functionalities and adsorbed on gold surfaces from ethanol solutions. The resulting film structures were characterized by atomic force microscopy (AFM), reflection Fourier-transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The experimental data indicate that a- or b-linked glucopyranosyl derivatives with free hydroxyl groups attach to gold via the thiol linker. Both derivatives form monolayer films with high packing densities - comparable to those typically observed for alkanethiol monolayers on gold.
