  • Title: Rhodium-catalyzed direct coupling of biaryl pyridine derivatives with internal alkynes.
    Author: Zheng J, You SL.
    Journal: Chem Commun (Camb); 2014 Aug 04; 50(60):8204-7. PubMed ID: 24931462.
    Abstract:
    Axially chiral biaryls were synthesized by an isoquinoline or 2-pyridine-directed Rh(III)-catalyzed dual C-H cleavage and coupling with internal alkynes in good to excellent yields. Oxidation of isoquinoline derivatives with m-CPBA furnished their corresponding N-oxides, which could be utilized as Lewis base catalysts in asymmetric reactions.
