  Sonication-Assisted Oligomannoside Synthesis

  摘要：

  We have investigated the use of sonication for the synthesis of oligomannosides. A convenient sonication-mediated glycosylation protocol that is applicable to traditional glycosylation methods has been developed. This protocol can be applicable for activating glycosyl donors that are known to have low reactivity which enable the synthesis of oligomannosides of particular biological interest with the same efficiency.
