A novel naphthylmethyleneimino-type protecting group for aliphatic and aromatic primary amines including α-amino acids was devised and its introduction was accomplished in good to excellent yields. This type of protecting group was found to be cleanly removed photochemically to regenerate the primary amines in good to high yields, regardless of steric and electronic properties.
设计了一种用于脂肪族和芳香族伯胺(包括 α-氨基酸)的新型萘亚甲基亚氨基型保护基团,并以良好到极好的收率实现了其引入。发现这种类型的保护基团可以通过光化学方法彻底去除,从而以良好到高产率再生伯胺,而不管空间和电子特性如何。
