Novel6-[N,N-bis(2-hydroxyethyl)amino]purine nucleosides were prepared in one step by nucleophilic substitution reaction of 6-choloropurine nucleosides with diethanolamine. Shorter reaction times and higher yields were achieved under microwave irradiation conditions in neat water.
This paper deals with the synthesis of nitrogenmustard analogs, derivatives of purine bases. Alkylation in position N-9 and diethanolamine fixation on position 6 were managed by microwave irradiations. Chlorination of these dihydroxylated intermediates led to a cyclization, giving tricyclic purine base analogs bearing a chloroethyl chain. Finally, MTT assays on obtained compounds do not show cytotoxicity
