  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.
