Cascading like dominos: An efficient and highly enantioselective synthesis of 2,3,4‐trisubstituted tetrahydroquinolines through cascade aza‐Michael–Michael reactions was developed. Tetrahydroquinolines were obtained in excellent yields, high enantioselectivities, and good diastereoselectivities, and could be easily transformed into ring‐fused tetrahydroquinolines (see scheme).
