  摘要：

  The synthesis of hyaluronan dimers and tetramers equipped with a 4-methylumbelliferyl group at the reducing end to potentially allow monitoring of hyaluronidase activities is described. The 4-OH at the non-reducing glucuronate in the presented series is either removed or methylated to prohibit transglycosylase reactions, leading to a total of four probes. (C) 2011 Elsevier Ltd.

• Dehydrative Glycosylation with the Hendrickson Reagent
  作者：Matteo Mossotti、Luigi Panza

  DOI：10.1021/jo2015856

  日期：2011.11.4

  The Hendrickson reagent is able to perform efficiently dehydrative glycosylation of 1-hydroxyglycosyl donors. The reaction occurs under mild conditions through an anomeric oxophosphonium intermediate detected by nuclear magnetic resonance. Further insight into the mechanism was gained by 18O labeling of anomeric OH.

  亨德里克森试剂能够有效地进行1-羟基糖基供体的脱水糖基化。该反应在温和条件下通过核磁共振检测到的异头氧代intermediate中间体而发生。通过18 O标记异头OH获得了对该机理的进一步了解。
