A conceptually new strategy has been described for the mild and environmentally friendly preparation of β-naphthylamines via Tf2O-activated cyclization of amides with alkynes. Both terminal and internal alkynes could serve as effective nucleophiles in this transformation. This chemistry features simple reaction conditions, high chemoselectivities, wide substrate scope, and offers a practical approach
已经描述了一种概念上的新策略,用于通过酰胺与炔烃的 Tf 2 O 活化环化来温和且环保地制备 β-萘胺。末端和内部炔烃都可以作为这种转化中的有效亲核试剂。该化学反应条件简单、化学选择性高、底物范围广,为多取代的β-萘胺提供了一种实用的方法。
