The development of an iron(III)-catalyzedsynthetic strategy toward functionalized tetrahydronaphthalenes is described. This approach is characterized by its operational simplicity and is distinct from currently available procedures that rely on [4 + 2]-cycloadditions. Our strategy takes advantage of the divergent reactivity observed for simple aryl ketone precursors to gain exclusive access to tetrahydronaphthalene
efficient AuIII‐catalyzed method to generate the highly reactive cyclic o‐quinodimethane (o‐QDM) species from easily available enynals or enynones is presented (see scheme). This method produced a variety of structurally unique fan‐like products with the advantages of mild reaction conditions, excellent diastereoselectivities, and high functional‐group tolerance.
