An efficient enantioselective cascade aza-Michael-Michael addition reaction catalysed by a chiral bifunctional tertiary amine-squaramide catalyst has been developed. This cascade reaction proceeded well under mild conditions, furnishing highly functionalized spirooxindole tetrahydroquinolines with three contiguous stereocenters in excellent yields with excellent diastereoselectivities (>25:1 dr) and high enantioselectivities (up to 94% ee).

An efficient reductive cyclization of o-nitrocinnamoyl compounds was achieved by employing a Hantzsch 1,4-dihydropyridine ester as a biomimetic reducing agent in the presence of catalytic palladium on carbon. This approach was successfully applied to the synthesis of substituted quinolines. Georg Thieme Verlag Stuttgart ? New York.
