(including phenolic hydroxy and carboxy) and mercapto groups. The NAPOM group can be introduced in extremely mild conditions (naphthylmethoxymethyl chloride, 2,6-lutidine, room temperature) without concomitant acyl migration in a 1,2-diol system. Furthermore, selective removal of NAPOM in the presence of naphthylmethyl (NAP) and p-methoxybenzyl (PMB) groups and, conversely, that of PMB in the presence of
开发2-萘甲氧基甲基(NAPOM)用于保护各种羟基(包括酚羟基和羧基)和巯基。NAPOM基团可以在极温和的条件下(萘甲氧基甲基氯,2,6-二甲基吡啶,室温)引入,而不会在1,2-二醇系统中伴随酰基迁移。此外,实现了在萘甲基(NAP)和对甲氧基苄基(PMB)基团存在下选择性去除NAPOM,以及相反在NAPOM存在下去除PMB。这些结果及其易于处理和与各种溶剂的相容性表明,NAPOM是一种新颖而有用的保护基。
