Iron‐Promoted Domino Dehydrogenative Annulation of Deoxybenzoins and Alkynes Leading to β‐Aryl‐α‐Naphthols

A strategy for synthesis of β‐aryl‐α‐naphthols has been established through an iron‐promoted domino C(sp3)−H/C(sp)−H and C(sp2)−H/C(sp)−H dehydrogenative coupling of deoxybenzoins and alkynes. The synthesis uses inexpensive materials with a broad substrate scope and features simple operations with excellent regioselectivity. This study provides an alternative access to various β‐aryl‐α‐naphthols and the synthetic protocol should have potential applications in medicinal, materials science, and related areas.
