Phenylated compounds
WebA control experiment with the 4-pyridinone furnished the expected N-phenylated compound with only 65% yield but with high selectivity. Both electron-donating and -withdrawing substituents on the pyridinone and diaryliodonium salts are well tolerated and led to the selective N-arylated compounds. Interestingly, the phenylation reaction was ... Webphenylated compound. WE have previously reported that N-dkylation of 6-methylthiopurines in aprotic solvents generally follows a single pathway (see Table 4). The direction of the
