  Diastereo- and enantioselective synthesis of N,O-nucleosides

  摘要：

  The diastereo- and enantioselective synthesis of alpha- and beta-3'-hydroxymethyl-N,O-nucleosides is described, based on the 1,3-dipolar cycloaddition of a N-glycosyl nitrone. Two approaches have been evaluated: the one-step procedure, which uses vinyl nucleobases, showed a better stereoselectivity towards beta-nucleosides. (C) 2003 Elsevier Ltd. All rights reserved.
