  Y(OTf)3 as a highly efficient catalyst in Ferrier Rearrangement for the synthesis of O- and S-2,3-unsaturated glycopyranosides

  摘要：

  By using Y(OTf)(3) as the catalyst, a series of 2,3-unsaturated-glucosides have been synthesized from 3,4,6-tri-O-acetyl-D-glucal, 3,4-di-O-acetyl-L-rhamnal, and 3,4,6-tri-O-benzyl-D-glucal under mild reaction conditions in good yields with high anomeric selectivities. It was found that, in this reaction, 3,4,6-tri-O-benzyl-D-glucal behaved differently from the other two glucals when it was reacted with phenol, O-benzyl glucoside instead of O-phenyl glucoside formed as the sole product. An explanation is given for this phenomenon. (C) 2014 Elsevier Ltd. All rights reserved.

  By using Gd(OTf)3 as the catalyst, synthesis of 2,3-unsaturated-glycosides has been performed by Ferrier Rearrangement. A series of 2,3-unsaturated O-, S-, N-, and C-glycosides were obtained from 3,4,6-tri-O-acetyl-d-glucal, 3,4,6-tri-O-benzyl-d-glucal, and 3,4-di-O-acetyl-l-rhamnal under mild reaction conditions in good yields and high anomeric selectivities.

  日期：——

  A temperature-controlled mechanism switch between the Al(OTf)3-catalysed direct addition of alcohols or the Ferrier rearrangement reactions in some glycals is presented. The scope and limitations are investigated as are the influence of the stereochemistry and nature of the protecting groups on the glycal substrate.
