Privileged biaryl frameworks,BINOL and NOBIN,were efficiently constructed with sole 1-DNQs as arylation reagents under one set of reaction conditions.The judicious selection of palladium-catalytic system plays a pivotal role in the excellent selectivities.This transformation accommodated fairly broad substrate generality for both 2-naphthol and N-Boc-2-naphthy-lamine and afforded the structurally diversified BINOLs and NOBIN derivatives in high efficiency.Notably,the bromo-substituents which cannot survive in conventional palladium-catalyzed reactions were well-compatible with this set of condi-tions,providing an effective handle for further enriching the library of BINOLs and NOBINs.Preliminary attempts on the asymmetric variant of this reaction were also performed with up to 80:20 er for BINOLs synthesis.
