  New Methodology for the Differentiation of the Primary Hydroxyl Groups in 2,3,3′,4,4′-Penta-O-Benzylsucrose: Convenient Approach to Sucrose Monophosphines

  摘要：

  Two new routes to derivatives of 2,3,3',4,4'-penta-O-benzylsucrose with differently protected primary hydroxyl groups were elaborated. One of these compounds, 2,3,3',4,4'-penta-O-benzyl-6'-O-mesylsucrose, was used in a model synthesis of the 6'-phosphine with sucrose scaffold. Elimination of the mesyloxy-group under the reaction conditions was also noted providing the 5',6'-unsaturated sucrose derivative.
