formation of polysubstituted 1-naphthols. The usage of readily available bromine catalyst, broad substrate scope, and mild conditions make this protocol very practical. Mechanistic investigations reveal that the bromination of phenylethanone derivatives occurs to yield bromo-substituted intermediates, which react in situ with alkynes to furnish the desired 1-naphthols.
Silver(I)-Catalyzed Regioselective Construction of Highly Substituted α-Naphthols and Its Application toward Expeditious Synthesis of Lignan Natural Products
developed for regioselective synthesis of highly substituted α-naphthols, binaphthols, and anthracenol through silver(I) catalyzed C(sp3)–H/C(sp)–H, C(sp2)–H/C(sp)–H functionalization of β-ketoesters and alkynes, respectively, in a single step using water as a solvent. This protocol exhibited broad substrate scope and paved the way for synthesis of anticancer arylnaphthalenelignan natural products such as

A new cyclization of β-keto ester substituted stilbene derivatives using selenium electrophiles in the presence of Lewis acids is described. Substituted naphthols are obtained through cyclization and subsequent 1,2-rearrangement of arylgroups under very mild reaction conditions.
