reaction between biaryl thionolactones and activated isocyanides is reported. Under auto-tandem silver catalysis, both tri- and tetra-ortho-substituted biaryls were obtained in high yields and enantioselectivities. These products could be converted to bridged biaryls bearing an eight-membered lactone. Mechanistic studies provided key insights into the cause of this unusual torsional strain-independent
