Electrocatalytic oxidative C–H cycloamination towards tricyclic [1,2,4]triazolo-[3,4-i]purine nucleosides mediated by bromide ions

A green and sustainable electrochemical alternative strategy for the synthesis of biologically important [1,2,4]-triazolo-[3,4- i ]-purine derivatives via intramolecular oxidative C–N bond coupling has been established.
