Research Interests

  • Stereochemical and other mechanistic aspects of chemical glycosylation. Novel glycosylation reactions.
  • Regioselective protection of carbohydrate molecules. Design and application of modern protecting groups and strategies to the synthesis of versatile building blocks.
  • Metal complexes in synthetic carbohydrate chemistry: direction of the stereoselectivity of glycosylation, regioselectivity, activation, temporary deactivation, switchable stereoselectivity, etc.
  • Expeditious strategies for the synthesis of complex oligosaccharides and glycoconjugates: chemoselectivity, and orthogonality of modern glycosyl donors.
  • Solid phase and surface chemistry: application to stereoselective glycosylation and rapid assembly of complex oligosaccharides and glycopeptides.
  • Combinatorial chemistry and automated synthesis.  New platforms and technologies for automated oligosaccharide synthesis: STICS and HPLC approaches.
  • Fully synthetic glycopharmaceuticals based on carbohydrates with potential biological activity (anti-cancer, anti-inflammatory, antiseptic, antibacterial, etc).
  • Synthetic glycoproteins, glycopeptides, glycopolymers, glycolipids, glycoheterocycles, glycoaminoacids and combinations thereof.  Synthetic glycoconjugate vaccines.
  • Human milk oligosaccharides and other food additives and ingredients. Oligosaccharides as prebiotics.
