| Abstract: | Quinazoline derivatives 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 quinazoline derivatives which may be useful in the synthesis of heterocyclic intermediates. |
| Keywords: | Quinazolines lmino-Diels-Alder reaction CuBr2 |
