Palladium-Catalyzed Aryl Amination Reactions of 6-Bromo- and 6-Chloropurine Nucleosides
{{output}}
Palladium-catalyzed C-N bond forming reactions of 6-bromo- as well as 6-chloropurine ribonucleosides and the 2'-deoxy analogues with aryl amines are described. Efficient conversions were observed with Pd(OAc)(2)/Xantphos/Cs(2)CO(3), in PhMe at 100 °C. Reactio... ...
