  Reexamination of Neomycin B Degradation:  Efficient Preparation of Its CD and D Rings as Protected Glycosyl Donors

  摘要：

  [GRAPHICS]The degradation of neomycin B was reexamined, and a novel protocol was established to prepare the properly masked neomycin CD ring as a glycol donor in excellent yield. Glycosylation of the CD ring with glycol acceptors provided a facile access to versatile intermediates that could be utilized to synthesize a variety of novel neomycin B mimetics for RNA recognition.
