A palladium-catalyzed direct synthesis of sym. biaryl compounds, e.g., 2,2′-dimethoxy-1,1′-biphenyl and 2,2′-dimethoxy-3,3′-bipyridine, from the corresponding aryl halides in the presence of tert-BuLi is described. In situ lithium-halogen exchange generates the corresponding aryl lithium reagent, which undergoes a homocoupling reaction with a second mol. of the aryl halide in the presence of the palladium catalyst (1 mol %). The reaction takes place at room temperature, is fast (1 h), and affords the corresponding biaryl compounds in good to excellent yields. The application of the method is demonstrated in an efficient asym. total synthesis of mastigophorene A (I). The chiral biaryl axis is constructed with an atropselectivity of 9:1 owing to catalyst-induced remote point-to-axial chirality transfer.
