the efficient α‐functionalization of amines, few strategies exist that enable the direct functionalization of amines in the β‐position. A general redox‐neutral strategy is outlined for amine β‐functionalization and α,β‐difunctionalization that utilizes enamines generated in situ. This concept is demonstrated in the context of preparing polycyclic N,O‐acetals from simple 1‐(aminomethyl)‐β‐naphthols and
与不断增长的允许胺有效 α 官能化的方法相反,很少有策略能够直接在 β 位官能化胺。概述了利用原位生成的烯胺进行胺 β 官能化和 α,β 双官能化的通用氧化还原中性策略。这个概念在从简单的 1-(氨甲基)-β-萘酚和 2-(氨甲基)-苯酚制备多环 N,O-缩醛的背景下得到了证明。
