of a divergent organocatalytic aza‐Michael/aldol cascade process towardquinolines and 1,4‐dihydroquinolines depends on the choice of the N‐protecting group (see scheme; TEA=triethylamine, TMS=trimethylsilyl). Use of an electron‐donating sulfonyl group results in an unanticipated aza‐Michael/aldol/aromatization cascade to give polysubstitutedquinolines (right). In contrast, chiral 1,4‐dihydroquinolines
