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

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.
