Scheme 2.

Scope of electrochemical synthesis of axially chiral biaryls. Reaction conditions: undivided cell, 2 (0.3 mmol), H₂O (1 mL), MeCN (9 mL), 3.5 F mol⁻¹. ^aIsolated yield of the major diastereomer. ^bDetermined by ¹H NMR analysis of crude reaction mixture. ^cCombined yield of the two diastereomers.
