  Synthesis of a branched oligosaccharide by remote glycosidation

  摘要：

  We describe a remote glycosidation that allows us to form a branched trisaccharide in intramolecular fashion. The molecular design of the spacer molecule for the remote glycosidation was examined based on molecular mechanics calculations. Copyright (C) 1996 Elsevier Science Ltd
