Аннотация

One-pot protocol metal-free oxidative C–H/C–H coupling of azines with 2-naphthols facilitated by Brønsted acid has been developed. The method affords azinylnaphthols, a basic scaffold of atropisomeric catalysts for asymmetric synthesis and fluorophores. The advantages of the proposed protocol include mild reaction conditions, high regio- and chemoselectivity and also scalability.
