  Stereoselectivities in the Coupling Reaction between Silylated Pyrimidine Bases and 1-Halo-2,3-dideoxyribose

  摘要：

  Coupling reactions between 1-chloro-2,3-dideoxyribose and silylated pyrimidines have been examined from the point of stereoselectivity. When the reaction was carried out in chloroform, the selectivity was in the anomeric ratio of alpha:beta = 4:6. On the other hand, the presence of tertiary amine raises the selectivity to alpha:beta = 3:7.
