formation or C–C bond formation upon homocondensation or reaction with simple olefins, respectively. Cyclization followed by a final oxidation generates these classes of interesting bioactive heterocycles in one synthetic transformation. Additionally, the one-pot multicomponent synthesis of quinolines from anilines, aldehydes, and olefins has also been successfully developed under these mild oxidative conditions

A one-pot synthesis of quinolines via molecular iodine-catalyzed and air-mediated tandem condensation/imino-Diels–Alder/isomerization/oxidation of simple readily available amines, aldehydes, and alkynes has been developed. This methodology was extended to synthesize quinazolines from two molecules of amines and two molecules of glyoxalates.

synthesis of structurally diverse 3,4-dihydroquinazolines from electron-rich arylamines, electron-poor arylamines and glyoxalates has been developed under mild conditions. This reaction is carried out in a tandem manner constituted by the condensation of arylamines and glyoxalates, the selective Diels–Alder cycloaddition and oxidation processes, in which 4-nitrothiophenol was used as the key ligand.

Quinazolinederivatives were synthesized from α-iminoesters via a cascade imino-Diels-Alder and then oxidation reaction catalyzed with CuBr2. This method provided a new strategy for preparing quinazolinederivatives which may be useful in the synthesis of heterocyclic intermediates.
