  Methylsulfonylethoxycarbonyl (Msc) and fluorous propylsulfonylethoxycarbonyl (FPsc) as hydroxy-protecting groups in carbohydrate chemistry

  摘要：

  The methylsulfonylethoxycarbonyl (Msc) group is presented as a non-lipophilic, base-labile, participating protecting group for carbohydrate alcohols. It can be introduced using Msc-Cl and pyridine and is readily cleaved via beta-elimination under mild basic conditions. Its fluorous counterpart, the perfluorooctyl propyl-sulfonylethoxycarbonyl (FPsc) group, is used in a 'light fluorous' trisaccharide synthesis sequence. (C) 2009 Elsevier Ltd. All rights reserved.
