主 题:Pyrrolo[1 2-a]quinoxaline a-Bromo ketones 1 2-Diamines Ethyl pyruvate
摘 要:A simple synthetic protocol has been developed involving the three-component reaction between 1,2-diamines, ethyl pyruvate and a-bromo ketones in the presence of Fe Cl3 as a catalyst. A number of pyrrolo[1,2-a]quinoxaline and pyrrolo[1,2-a]pyrazine derivatives were synthesized in excellent yields using this protocol.
