## Abstract Allopurinol and 4‐amino‐1H‐pyrazolo[3,4‐d]pyrimidine N^1^‐and N^2^‐(D‐arabinofuranosides) have been synthesized. Nucleobase anion glycosylation of 4‐methoxy‐1H‐pyrazolo[3,4‐d]‐pyrimidine (7) with the α‐D‐arabinofuranosyl chloride 6a proceeds stereoselectively and affords the N^1^‐(β‐D‐n
