  Synthesis, structural, and biological studies on a pseudodisaccharide containing a bicyclic, bridged carba-sugar

  摘要：

  Two carba-sugar containing pseudodisaccharide diastereomers have been synthesized from a racemic bicyclooctene derivative. The determination of the absolute configurations was carried out by means of CD measurements, CD calculations and X-ray diffraction. The compounds showed moderate competitive inhibitory effects on chondroitin AC-I lyase. (C) 2011 Elsevier Ltd. All rights reserved.
