  Direct Arylation of Adenine by Fluoro- and Chloronitrobenzenes: Effect of Microwaves

  摘要：

  Direct arylation of adenine with fluoro- and chloronitrobenzenes leads to mixtures of N9 and N7 substituted adenines. After separation by column chromatography, the individual isomers can be efficiently hydrogenated on Pd to give the corresponding aminophenyladenines. A significant enhancement of the reaction rate by microwave irradiation was observed. This two-step procedure was found to be a feasible route to otherwise hardly available 7-aminophenyladenines. Correlation between calculated shielding constants and experimental values of chemical shifts in C-13 and N-15 NMR was used for assignment of the site of substitution.

  Abstract N‐Arylation of some pyrimidine and purine nucleobases in the presence of SiO2 and Cs2CO3 under solvent‐free as well as in solution conditions is described. In these conditions, N1‐aryl pyrimidines and N9‐aryl purines have been obtained regioselectively in moderate to high yields with relatively short reaction times.

  A highly efficient and simple method for the synthesis of N-aryl derivatives of pyrimidine and purine nucleobases via N-arylation of nucleobases using zinc oxide in 1-butyl-3-methylimidazolium bromide ([bmim]Br) under microwave as well as thermal conditions is described. In both conditions, the title compounds were produced in high to excellent yields and in short reaction times.
