  Synthesis of Novel α,ω-Type 1-Glucosamide and 1-Galactosamide Bolaamphiphiles

  摘要：

  A new family of bolaamphiphiles in which two glucosylamine or galactosylamine moieties are linked via a beta-N-glycosidic bond to an alpha,omega-dicarboxylic acid has been described. The 1-D-glucosamide and 1-D-galactosamide bolaamphiphiles were obtained in good yield by the condensation of the dicarboxylic acid dichloride with the corresponding 1-aldopyranosylamine.

• Stereochemical Effect of Even−Odd Connecting Links on Supramolecular Assemblies Made of 1-Glucosamide Bolaamphiphiles

  Bolaamphiphiles with a 1-glucosamide-head group at each end, N,N'-bis(beta-D-glucopyranosyl)alkane-1, n-dicarboxamide [Glc-NC(n)CN-Glc, n=6, 9, 10, 11, 12, 13, and 14], have been synthesized. Self-assembled supramolecular structures in water strongly depend on whether a is even or odd, which respectively give rise to fibrous assemblies or planar platelets as well as amorphous solids. In connection with this even-odd effect of the hydrocarbon links, internal molecular arrangements of the solid fibers were investigated using FT-IR spectroscopy, X-ray diffraction and crystal analyses, and transmission electron microscopy. The oligomethylene groups of the Glc-NC(12)CN-Glc pack in a monoclinic or an orthorhombic mode in the fiber. We propose a possible self-assembled model based on a monolayer sheet, which is stabilized by hydrogen-bond networks via sugar-head and amide groups.
