A mild and practical protocol for highly regioselective C6−Halkylation of purines with alcoholsintervened by oxalates under blue LED irradiation is reported. This transformation does not need transition metalcatalysts, is not sensitive to moisture and does not require N2 protection. Besides, this method displays broad functional groups compatibility and is easily scale up.
