Exploring the synthetic potency of the first furanothioglycoligase through original remote activation

Thioglycosidic bonds are of utmost importance in biomolecules as their incorporation led to more stable glycomimetics with potential drug activities. Until now only chemical methods were available for their incorporation into glycofuranosyl conjugates. Herein, we wish to describe the use of the first furanothioglycoligase for the preparation of a great variety of thioaryl derivatives with moderate to excellent yields. Of great interest, a stable 1-thioimidoyl arabinofuranose, classically used in chemical glycosylation, was able to efficiently act as a donor through an original enzymatic remote activation mechanism. Study of the chemical structure as well as the nucleophilicity of the thiol allowed us to optimize this biocatalyzed process. As a consequence, this mutated enzyme constitutes an original, mild and eco-friendly method of thioligation. The Royal Society of Chemistry 2011.

Successful combination of (methoxydimethyl)methyl (MIP) and (2-naphthyl)methyl (NAP) ethers for the synthesis of arabinogalactan-type oligosaccharides

In order to characterise the presumed epitopes of arabinogalactans, isolated from the extract of the cell-cultured Echinacea purpurea, two oligosaccharides were synthesized. The whole synthetic route was based on the successful combination of the (methoxydimethyl)methyl (MIP) and the (2-naphthyl)methyl ether (NAP) protecting groups. A β-(1→6)-linked trigalactoside was prepared, which contained a NAP ether at position 2′.This protecting group was selectively removed using either DDQ or Pd-C/H2 and the acceptor was ready for further glycosylation. We have used two arabinofuranosyl donor compounds: 2,3,5-tri-O-acetyl arabinofuranosyl trichloroacetimidate and a peracetylated α-(1→5)-linked diarabinofuranosyl trichloroacetimidate. For the deprotection of the tetra- and pentasaccharides a common procedure was used. All of the synthesized compounds were characterized by 1H and 13C NMR spectroscopy, as well as by MALDI-TOF mass-spectrometry.
