  Transformation of linear oligoketosides into macrocyclic neoglycoconjugates

  摘要：

  The macrocyclization of linear D-galacto-2-heptulopyranose-containing oligoketosides has been carried out by intramolecular glycosidation and ring-closing metathesis. The aglycon fragment of the cyclic neglycoconjugates thus formed was an alkylidene or a polyether chain. One of the oligoketoside-crown ethers showed a moderate asymmetric induction in the Cram model phenyl acetate-acrylate addition. (C) 2009 Elsevier Ltd. All rights reserved.
