A new synthesis of biaryls.

Cyclohexadienone Ketals and Quinols: Four Building Blocks Potentially Useful for Enantioselective Synthesis

“…Kurihara has devised an intermolecular variant of this process for the synthesis of biaryl compounds (Figure ) . Treatment of the p -quinol 644 with a Lewis acid in the presence of various benzene derivatives affords the biaryl derivative 643 .…”
