Nature offers a huge diversity of glycosidic derivatives. Among numerous structural modulations, the nature of the ring size of hexosides may induce significant differences on both biological and physicochemical properties of the glycoconjugate of interest. On this assumption, we expect that small disaccharides bearing either a furanosyl entity or a pyranosyl residue would give a specific signature, even in the gas phase. On the basis of the scope of mass spectrometry, two analytical techniques to register those signatures were considered, i.e., the ion mobility (IM) and the infrared multiple photon dissociation (IRMPD), in order to build up cross-linked databases. d-Galactose occurs in natural products in both tautomeric forms and presents all possible regioisomers when linked to d-mannose. Consequently, the four reducing Galf-Manp disaccharides as well as the four Galp-Manp counterparts were first synthesized according to a highly convergent approach, and IM-MS and IRMPD-MS data were second collected. Both techniques used afforded signatures, specific to the nature of the connectivity between the two glycosyl entities.

The preparations of α(1,2)-, α(1,3)- and α(1,6)-linked mannose disaccharides is described.The protected α-D-Man(1-->3)-D-Man disaccharide was synthesized using the trichloroacetimidate method, while the Koenigs-Knorr procedure was employed in the preparation of the 1-->2- and 1-->6-linked disaccharides.Glycosylation of NΑ-Fmoc-Ser-OPfp , Nα-Fmoc-Thr-OPfp and Nα-Fmoc-Hyp-OPfp with the dimannosyl bromides afforded the activated building blocks, in moderate to high yield, for direct use in solid-phase synthesis of glycopeptide libraries.

Iodonium ion (NIS/TfOH)-assisted glycosylation of a sugar acceptor with properly protected ethyl (phenyl) 2-O-phenoxythiocarbonyl 1-thio-β-D-gluco- or 1-thio-α-D-mannopyranoside donors gives the respective 1,2-trans linked 2'-ethyl (phenyl) thio-2'-deoxy-α-D-manno- or β-D-glucopyranosides.
