Solid support synthesis of tetrahydroquinolines via the Grieco three component condensation
Kiselyov, Alexander S.,Armstrong, Robert W.
, p. 6163 - 6166 (1997)
A three component condensation involving aromatic amines, aldehydes, alkenes and TFA as a catalyst affords the desired tetrahydroquinolines in good yields. A variety of structures for the olefin and aldehyde inputs in the library were investigated.
Inter- and Intramolecular Imino Diels-Alder Reactions Catalyzed by Sulfamic Acid: A Mild and Efficient Catalyst for a One-Pot Synthesis of Tetrahydroquinolines
Nagarajan, Rajagopal,Magesh, Chinnan J.,Perumal, Paramasivan T.
, p. 69 - 74 (2007/10/03)
The successful use of sulfamic acid as a catalyst in the inter- and intramolecular Inverse Electron Demand Diels-Alder reactions of iminodienes is described. A one-pot synthesis of tetrahydroquinolines was achieved by three component coupling of benzaldeh
Inverse electron demand Diels-Alder reactions of heterodienes catalyzed by potassium hydrogen sulfate: Diastereoselective, one-pot synthesis of pyranobenzopyrans, furanobenzopyrans and tetrahydroquinolines derivatives
Kumar, R. Senthil,Nagarajan, Rajagopal,Perumal, Paramasivan T.
, p. 949 - 959 (2007/10/03)
Potassium hydrogen sulfate catalyzes the one-pot three components coupling of aldehydes, anilines, and electron rich dienophiles such as dihydropyran, dihydrofuran, ethyl vinylether, and cyclopentadiene. With o-hydroxybenzaldehyde, the reaction probably p

Triphenyl phosphonium perchlorate (TPP) is found to be an efficient catalyst for the imino Diels-Alder reaction of aldimines with cyclopentadiene and 3,4-dihydro-2H-pyran is reported for the first time. One pot synthesis of furoquinoline, cyclopentaquinol
ROLE REVERSAL IN THE CYCLOCONDENSATION OF CYCLOPENTADIENE WITH HETERODIENOPHILES DERIVED FROM ARYL AMINES AND ALDEHYDES: SYNTHESIS OF NOVEL TETRAHYDROQUINOLINES
Grieco, Paul A.,Bahsas, Ali
, p. 5855 - 5858 (2007/10/02)
Immonium ions derived from aryl amines and aldehydes function not as heterodienophiles but rather as heterodienes in the presence of cyclopentadiene giving rise to novel tetrahydroquinolines.
