  Synthesis of Ether-Linked Oligoribo- and Xylonucleosides from 3,5′-Ether-Linked Pseudosaccharides

  摘要：

  First examples of di- and trinucleosides with ribose and xylose stereochemistry having internucleoside ether linkage were synthesized from 3,5'-ether-linked pseudosaccharides. The synthetic protocol involved removal of 1,2-isopropylidene protecting groups front the pseudosaccharides followed by acetylation and a subsequent Vorbruggen transglycosylation with uracil and N-benzoylaminopurine. The synthetic strategy is potentially important for the development of RNA analogues with internucleoside ether linkage.
