Significance

1,4-Dihydropyridines have been recognized as a potential source of hydrogen when undergoing dehydroaromatization. Such strategy has been exploited here for highly enantio­selective hydrogenation of quinolines. Reduction proceeds smoothly under mild conditions and minimal investment of the catalyst to give a variety of amine products. The reaction is sensitive to the electron-withdrawing substituents in the 6-position which cause decreased reactivity.
