As an extension of organic photochemistry via intermolecular electron-transfer in donor-acceptor pair systems between electron-rich aromatic compounds and electron-deficient tosyl groups, we report here a new protecting group for the amino function, 4-(4,8-dimethoxynaphthylmethyl)benzenesulfonyl (DNMBS) group, which is readily removed, via an intramolecular electron-transfer followed by hydrolysis, with
作为有机光化学在富电子芳族化合物和缺电子的甲苯磺酰基之间的供体-受体对系统中通过分子间电子转移的扩展,我们在此报告了一种新的氨基官能团保护基团,4-(4,8-二甲氧基萘甲基)苯磺酰基(DNMBS)基团,通过分子内电子转移然后水解,可以很容易地除去,并且在用大于300 nm的光照射时具有很高的量子效率。
