Regioselective alkylation reaction of purines under microwave irradiation

The alkylation of purines which is generally carried out after anion formation by treatment with a base and alkyl halide is complicated and in the best cases, mixtures of N-alkylated compounds are obtained. Purine derivatives can be acquired from alkylation at N-7 and N-9. In this work, the reaction...
