An unequivocal synthesis of 9-allyladenine 1-oxide (III) has been accomplished by an initial alkylation of 1-ethoxyadenine (VI) with allyl bromide and the Et-O bond cleavage of the resulting 9-allyl-1-ethoxyadenine hydrobromide (VII) with pyridine. 9- (Δ2-Isopentenyl)adenine 1-oxide (IX) was also prepared in a similar manner.
