The alkylation of purines which is generally carried out after anion formation by treatment with a base and alkyl halide complicated in the best cases, mixtures N-alkylated compounds are obtained. Purine derivatives can be acquired from at N-7 N-9. In this work, reaction conditions have been optimized to obtain products N-9 regioselectively. Different bases tried tetrabutylammonium hydroxide ha...

External funding is of course of major importance for research progress. This term, FyFa researchers were capable to attract more than 20 Milj kr (22,05 Milj kr) from the Swedish Research Council (for details and abstracts of the projects check www.vrproj.vr.se – project database). Even though, FyFa was very successful with 1 network grant (G. Engberg) and 9 project grants (A. Arner, B. Canlon,...
