Practical one-pot procedure for the synthesis of 1,2,3,4- tetrahydroquinolines by the imino-Diels-Alder reaction
Dehnhardt, Christoph M.,Espinal, Yomery,Venkatesan, Aranapkam M.
, p. 796 - 802 (2008)
A novel-one-pot procedure for the synthesis of tetrahydroquinolines via the imino-Diels-Alder reaction is described. This procedure gives better yields and exhibits better versatility for alkene substrates than the existing hemi-aminal based methodologies
Intermolecular Polar Cycloadditions of Cationic 2-Azabutadienes from Thiomethylamines: A New and Efficient Method for the Regio- and Diastereo-selective Synthesis of 1,2,3,4-Tetrahydroquinolines
Beifuss, Uwe,Ledderhose, Sabine
, p. 2137 - 2138 (1995)
Substituted 1,2,3,4-tetrahydroquinolines and related condensed nitrogen-heterocycles are formed highly regio- and diastereo-selectively with yields ranging from 57 to 100percent by intermolecular polar cycloadditions of cationic 2-azabutadienes
One-pot synthesis of tetrahydroquinolines catalyzed by Dy(OTf)3 in aqueous solution
Chen, Ruifang,Qian, Changtao
, p. 2543 - 2548 (2002)
Various 4-substituted-1-methyltetrahydroquinolines are easily accessible from the one-pot condensation reaction of N-methylaniline with commercial formaldehyde solution and electron-rich alkenes in the presence of Dy(OTf)3 (1 mol %) under mild
Practical synthetic strategies towards lipophilic 6-iodotetrahydroquinolines and -dihydroquinolines

The synthesis of novel tetrahydroquinolines (THQ) and dihydroquinolines (DHQ) are reported using three practical, scalable synthetic approaches to access highly lipophilic analogues bearing a 6-iodo substituent, each with a different means of cyclisation. A versatile and stable quinolin-2-one intermediate was identified, which could be reduced to the corresponding THQ with borane reagents, or to the DHQ with diisobutylaluminium hydride via a novel elimination that is more favourable at higher temperatures. Coupling these strongly electron-donating scaffolds to electron-accepting moieties caused the resulting structures to exhibit strong fluorescence.
