Purines. LXIX. Direct N(1)-Oxidation of 7-Benzyladenine and Stepwise Syntheses of Its N(1)- and N(3)-Oxides

In contrast to the N(3)-selectivity in N-alkylation, N-oxidation of 7-benzyladenine (17) with m-chloroperoxybenzoic acid in MeOH has been found to give 7-benzyladenine 1-oxide (18) in 76% yield. Alternatively, the same N-oxide (18) has been synthesized in 81% yield from 1-benzyl-4-(ethoxymethyleneam...
