structural feature of many natural products. By using a domino reaction of aromatic amines and cyclicenolethers or 2-hydroxy cyclicether catalyzed by indium chloride in water, various tetrahydroquinoline derivatives were synthesized efficiently. Most cyclization products showed cis selectivity. The use of 2,3-dihydrofuran as the cyclicenolether provided both higher reactivity and cis selectivity than

A highlyefficient method for the synthesis of 1,2,3,4-tetrahydroquinoline derivatives via a molecular iodine catalyzed dominoreaction of anilines with cyclic enol ethers, such as 2,3-dihydrofuran and 3,4-dihydro-2H-pyran, is described. The reaction may proceed through an aza-Diels–Alder process between an in situ generated 2-azadiene and another equivalent of cyclic enol.

Natural supramolecular carbohydrate scaffold-catalyzed synthesis of tetrahydroquinoline derivatives by the reaction of aromatic amine and cyclicenolether in excellent yield with high diastereoselectivity has been developed. Carbohydrates, cellulose, and starch were converted into their sulfonic acid derivative and these scaffolds exhibit efficient catalytic properties, along with excellent cost effectivity

A domino reaction of anilines with cyclic and acyclic enolethers induced by catalytic amounts of TBPA+ (5 mol%) was investigated and a series of 2,4-disubstituted-1,2,3,4-tetrahydroquinolines were synthesized. Different from cyclic enolethers, when acyclic enolethers were used in the reaction, they serve as surrogates of acetaldehyde, producing a series of 2-methyl-4-anilino-1,2,3,4-tetrahydroquinolines
