Studies on quinoline and isoquinoline derivatives. VIII. Hydration and hydrogenation of ethynyl substituents attached to the pyridine moiety of quinoline and isoquinoline rings.
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
