  Versatile and self-assembling urea-linked neosaccharides from sugar aminoalcohols

  摘要：

  The increasing interest in urea compounds as self-assembling molecules, ion transporters and organo-catalysts prompted several efforts towards synthetic urea-linked glycomimetics. In this frame we studied in details a novel two steps dimerization reaction of sugar vicinal aminoalcohol building blocks, opening a synthetic path to a series of urea-linked neosaccharides. Glucosamine neodisaccharide possessing an oxazolidinone-urea-oxazolidinone system could be transformed into both cyclic and higher linear neosaccharides. Furthermore, a series of six urea-linked glucosamine and galactosamine neodisaccharides was tested for self-assembling properties by measuring NMR spectra at different temperatures and concentrations as well as by gelation of several organic solvents.

  A novel urea-linked glucosamine dimer was obtained through a modification of the standard oxazolidinone closure reaction on a 2,3-amino alcohol monomer and fully characterized by NMR spectroscopy and by molecular mechanics and dynamics techniques. A mechanism was proposed for the dimerization reaction that was based on the formation of a 2,3-bis[(p-nitrophenoxy)carbonyl] intermediate. Chemoselective
