  Stereoselective synthesis of thioxylooligosaccharides from S-glycosyl isothiourea precursors

  摘要：

  A stereoselective synthesis of thioxylo-di-, -tri-, -tetra- and -penta-saccharides from S-glycosyl isothiourea precursors is described. The synthesis was performed starting from 2,3,4-tri-O-acetyl-beta -D-xylopyranosyl isothiouronium bromide using a triethylamine promoted reaction with 1,2,3-tri-O-benzoyl-4-O-lrifluoromethanesuIphonyl-beta -L-arabinopyranose. The resulting 4-thioxylobisse was then converted into the corresponding isothiouroniurn bromide and used for the synthesis of 4,4 ' -dithioxylotriose. Higher homologues of the series and their alpha -methyl glycosides were also prepared. (C) 2001 Elsevier Science Ltd. All rights reserved.

  interactions responsible for the self-assembly of gelators through IR spectroscopy and wide-angle X-ray scattering reveal that the primary interactions responsible are hydrogen bonds between the hydroxyl groups and ester C=O, which is absent in the solid state of the gelators. In addition, π interactions present in the 1,2-dibenzoylated derivative result in a more regular arrangement, which, in turn, leads

  糖基低分子量胶凝剂（LMWG）长期以来一直用于各种应用。在本文中，据报道结构简单的酯保护的阿拉伯糖苷是能够使芳族溶剂以及汽油和柴油胶凝的低分子量有机胶凝剂（LMOG）。通过详细的流变实验对凝胶的机械强度进行的研究表明，与1,1,2-二乙酰化凝胶剂相比，1,2-二苯甲酰化阿拉伯糖凝胶剂的凝胶具有更好的机械性能。根据详细的场发射SEM和AFM研究，可以根据前者形成直径比后者直径小的纤维的趋势来解释这些结果。通过红外光谱和广角X射线散射对负责胶凝剂自组装的相互作用的研究表明，负责相互作用的主要相互作用是羟基和酯C = O之间的氢键，而氢键在固态时不存在。胶凝剂。另外，存在于1，2-二苯甲酰化衍生物中的π相互作用导致更规则的排列，与1，2-二乙酰化的胶凝剂相比，其进而导致凝胶的更好的机械性能。
