Versatile use of 4-nitrobenzyl group for protection of hydroxyl functions is described. It can be removed selectively in the presence of other benzyl-type protecting groups such as benzyl and 4-methoxybenzyl via reduction into 4-aminobenzyl group followed by electrochemical oxidation. Very clean oxidative cleavage of 4-aminobenzyl group could also be effected with 2,3-dichloro-5,6-dicyanobenzoquinone
描述了广泛使用4-硝基苄基来保护羟基官能团。可以在存在其他苄型保护基如苄基和4-甲氧基苄基的情况下,通过还原成4-氨基苄基,然后进行电化学氧化,选择性地将其除去。N-乙酰化后,用2,3-二氯-5,6-二氰基苯并醌也可以非常干净地氧化4-氨基苄基。
