quinolin-3-amines. 2-(2-Isocyanophenyl)acetonitriles and organoboronreagents are suitable substrates for this reaction. The remarkable advantages of this protocol are the practical method, mild approach, high reaction efficiency, and good compatibility of functional groups, providing straightforward access to functional quinoline derivatives.
A chiral phosphoric acid catalyzed asymmetric transfer hydrogenation of aromaticamines, quinolin-3-amines, was successfully developed with up to 99% ee. To supplement our previous work on the Ir-catalyzed asymmetrichydrogenation of 2-alkyl substituted quinolin-3-amines, a number of 2-aryl substituted substrates were reduced to provide a series of valuable chiralexocyclicamines with high diastereo-
