An organocatalytic enantioselective Michael addition/aza-cyclization cascadereaction of aldehydes with 2-amino-β-nitrostyrenes has been developed for the construction of fully substituted chiral tetrahydroquinolines. The reaction, promoted by diphenylprolinol TMS ether as an organocatalyst, generated the chiral tetrahydroquinolines in good to high yield with excellent diastereo- and enantioselectivities
