Application of HOF·CH3CN to the synthesis of glycosyl sulfones
摘要:
A fast, complete and clean conversion of thioglycosides into glycosyl sull'ones under mild acidic conditions is described, using the HOF center dot CH3CN complex at room temperature. This methodology affords glycosyl sull'ones in high yields and in excellent purity. (c) 2008 Elsevier Ltd. All rights reserved,

The synthesis of 1,1-thiodisaccharide trehalose analogues in good to excellent yields by a Lewis acid (BF3 center dot Et2O)-catalysed coupling of sugar per-O-acetate with thiosugar is described. The reactivity of different sugar per-O-acetates and thiosugars is explored. (C) 2009 Elsevier Ltd. All rights reserved.
