A new approach for the efficient and convenient synthesis of novel aminoalkyl-functionalized
4-arylquinolines via the Friedländer reaction of differently substituted 2-(3,4-dihydroisoquinolin-1-yl)anilines
with various α-methylene ketones in acetic acid was developed. The reaction allows
easy access to a diversity of 4-arylquinoline derivatives in moderate to excellent
yields under mild conditions.
