A facile preparation of trehalose analogues: 1,1-thiodisaccharides
摘要:
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.
