the application! An enantioselective synthesis of axially chiral 1‐arylisoquinolines has been achieved, which involves a rhodium‐catalyzed [2+2+2] cycloaddition of diphenylphosphinoyl‐substituted 1‐arylisoquinolines (see scheme). The new diphenylphosphinoyl‐substituted axially chiral 1‐arylisoquinolines were successfully derivatized to the corresponding axially chiral P,Nligand and Lewis base catalyst
