We report here a multicomponent protocol to assemble several polycyclic dihydropyran-fused tetrahydroquinoline structures with excellent diastereoselectivity. This procedure employs simple feedstocks to accomplish a series of diverse structures, which is
Visible-Light Induction/Br?nsted Acid Catalysis in Relay for the Enantioselective Synthesis of Tetrahydroquinolines

An efficient method merging Br?nsted acid catalysis with visible-light induction for the highly enantioselective synthesis of tetrahydroquinolines has been developed. This mild process directly transforms 2-aminoenones into 2-substituted tetrahydroquinolines with excellent enantioselectivities through a relay visible-light-induced cyclization/chiral phosphoric acid-catalyzed transfer hydrogenation reaction.

An organocatalytic asymmetric method for the synthesis of 2-CF3 tetrahydroquinoline has been achieved. The cascade reaction of 2-aminochalcones with β-CF3 nitroalkenes afforded the products bearing three contiguous stereogenic centers in good yields with excellent diastereoselectivities and enantioselectivities.
Organocatalyzed aerobic oxidative Robinson-type annulation of 2-isocyanochalcones: expedient synthesis of phenanthridines

A DBU-catalyzed aerobic oxidative Robinson annulation of 2-isocyanochalcones with active methylene ketones was developed for the expedient synthesis of phenanthridines in high to excellent yields. This unprecedented multistep domino reaction represents a
Cinchona-based squaramide-catalysed cascade aza-Michael-Michael addition: Enantioselective construction of functionalized spirooxindole tetrahydroquinolines
Yang, Wen,Du, Da-Ming
, p. 8842 - 8844 (2013/09/24)
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).
