A synthetic method for the construction of fully substituted enantioenriched 1,4‐dihydroquinolines using an organocatalytic aza‐Michael/Michael cascadereaction has been developed. The asymmetricreaction of 2‐(tosylamino)phenyl α,β‐unsaturated ketones with alkynyl aldehydes, promoted by diphenylprolinol O‐TMS ether as an organocatalyst, generated chiral 1,4‐dihydroquinolines in good to high yields
