A method of synthesis of a 2-substituted adenosine of formula I which comprises converting a compound of formula II to a compound of formula (I), wherein: R is C 1-6 alkoxy (straight or branched), a phenoxy group (unsubstituted, or mono-, or di-substituted by halo, amino, CF3-, cyano, nitro, C 1-6 alkyl, or C 1-6 alkoxy), a benzyloxy group (unsubstituted, or mono-, or di-substituted by halo, amino, CF3-, cyano, nitro, Cl_6 alkyl, or Cl_6 alkoxy), or a benzoyl group (unsubstituted, or mono-, or di-substituted by halo, amino, CF3-, cyano, nitro, C 1-6 alkyl, or C 1-6 alkoxy); R' = H, or a protecting group.
一种合成式I的2-取代腺苷的方法,包括将式II的化合物转化为式(I)的化合物,其中:R为C 1-6烷氧基(直链或支链)、苯氧基(未取代或经氟、氨基、CF3-、氰基、硝基、C 1-6烷基或C 1-6烷氧基单取代或双取代)、苄氧基(未取代或经氟、氨基、CF3-、氰基、硝基、Cl_6烷基或Cl_6烷氧基单取代或双取代)或苯甲酰基(未取代或经氟、氨基、CF3-、氰基、硝基、C 1-6烷基或C 1-6烷氧基单取代或双取代);R' = H或保护基。
