The synthesis of polysubstituted quinolines can be easily and greenly accomplished by the direct reaction between the corresponding 2-aminobenzylic alcohol derivative and either a ketone or alcohol in the presence of a base, without any transition-metal catalyst.

日期:2007.4
The first synthesis of polysubstituted quinoline derivatives from aromatic or aliphatic alcohols with RuCl2(dmso)4 as catalyst under solvent-free conditions is described. The reaction involves the in situ oxidation of alcohols to the corresponding carbonyl compounds through a hydrogen-transfer, followed by a Friedlander annulation process. The whole process is a mild, efficient, selective, and high-yielding
Copper-Catalyzed Synthesis of Substituted Quinolines via C–N Coupling/Condensation from <i>ortho</i>-Acylanilines and Alkenyl Iodides

An efficient cascade copper-catalyzed intermolecular Ullmann-type C–N coupling/enamine condensation reaction is described, in which ortho-acylanilines and alkenyl iodides converted to multisubstituted quinolines in good to excellent yields.
alcohols, benzaldehydes, and DMSO to quinolines has been disclosed. For the reported annulation between 2-aminobenzyl alcohols and benzaldehydes, the change of the solvent from toluene to DMSO led to the change of the product from the diheteroatomic cyclic benzoxazines to monoheteroatomic cyclic quinolines. This annulation can be used to synthesize regioselectively different substituted quinolines
