  Oligosaccharide Analogues of Polysaccharides, Part 17, Synthesis and Characterization of a Hexadecamer: Evidence for the Essential Structural Role of the Intramolecular, Interresidue C(3)−OH⋅⋅⋅O−C(5) Hydrogen Bond in Celluloses

  摘要：

  The hexadecamer 63 dissolves readily in DMSO and shows no sign of association, in agreement with the essential structural role of the intramolecular, interresidue C(3)-OH ... O-C(5) H-bond of celluloses, MM3 Calculations predict a rod-like shape for the cello-oligosaccharides In agreement with this, nanocrystalline domains of parallel chains are observed by high-resolution electron microscopy (HREM) for 54 and 63 on carbon-coated copper grids. For the synthesis of the hexadecamer 54, we studied the influence of protecting groups on the cross-coupling of acetyleno-oligosaccharides and on their solubility (Scheme 2). The octamer 12 derived from the minimally O-protected monomer 2 is insoluble, while the methoxymethyl- and triisopropysilyl-protected hexadecamer 54 prepared in twelve steps from the dimer 41 (Scheme 4), is readily soluble in a variety of solvents. O- and C-deprotection of 54 led in four steps and in 76% yield to the hexadecamer 63 (Schemes 5 and 6). There is only a small difference of spectroscopic properties between the protected octamer 50 and hexadecamer 54, and, similarly, between the unprotected octamer 64 and hexadecamer 63 (Fig. 3).

  Oligosaccharide Analogues of Polysaccharides, Part 16, Cross-Coupling of Partially Protected Dialkynyl Monosaccharides

  摘要：

  The dependency of the cross-coupling of orthogonally C-protected dialkynyl monosaccharides on the nature of the coupling partners has been studied, The required dialkyne 5 was synthesized from levoglucosan in six steps and 39% overall yield and transformed into 7 10, 12, 13, and 14 by orthogonal C-deprotection and bromination (Scheme 1). Optimization of the conditions of their cross-coupling to 16 showed that yields were higher for the coupling of the propargylic bromoalkyne 10 than for the homopropargylic bromoalkyne 14 (Scheme 2). Deprotection of 16 gave the nano-crystalline dimer 20. To obtain more highly crystalline products, the monomers 7 and 13 were coupled with 1-iodo-4-nitrobenzene to the arylated monomers 21 and 24 (Scheme 3). The 4-NO2C6H4, substituent lowered the yield of the dimerizations to the mono- and diarylated dimers 26-28 (Scheme 4) but had no effect on crystallinity.
