important quinoxaline derivatives were efficiently synthesized in excellent yields by the reaction of 1,2-diketones and 2-nitroaniline, benzofuroxan or 1,2-dinitrobenzene promoted by SnCl22H2O. The role of stannous chloride is acting as both reductive agent and catalyst in this synthesis. This new method has the advantages of accessible starting materials, convenient manipulation, short reaction time
通过SnCl 2 2H 2 O促进的1,2-二酮与2-硝基苯胺,苯并呋喃或1,2-二硝基苯的反应,可以高收率高效合成各种生物学上重要的喹喔啉衍生物。氯化亚锡既起还原作用,又起还原作用合成中的助剂和催化剂。该新方法具有原料易得,操作方便,反应时间短和产率高的优点。
