  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.

  日期：——

  New synthetic routes to complex sucrose derivatives are presented. They are based on a highly selective silylation of the hydroxyl group at the C6' position ('fructose end') in 2,3,3',4,4'-penta-O-benzylsucrose followed by functionalization of the remaining (C-1',6) positions. One of these synthons was used as a chiral platform for the construction of aza-macrocyclic systems.
