title: Introduction of a benzoyl group onto 6-chloropurine riboside in aqueous solution and its application to the synthesis of nucleoside derivatives.
abstract: A benzoyl group was introduced onto the 3'-hydroxyl group of 6-chloropurine riboside by treatment with benzoic anhydride in the presence of a base in aqueous solution. The product (3b) was converted to 9-(2,3-Di-deoxy-2-fluoro-beta-D-threo-pentofuranosyl)adenine (1, FddA) in 6 steps, including radical deoxygenation.
