An efficient copper-catalyzed synthesis of substituted 2,4-diamino-1,3,5-triazines from 1,1-dibromoalkenes and biguanides under mild conditions has been developed. The reaction occurred in moderate to good yields and tolerated alkyl-, heterocyclic-, or aryl-substituted 1,1-dibromoalkenes containing functionalities such as nitriles, ethers, and halogens. Monosubstituted to tetrasubstituted biguanidines
已经开发了在温和条件下由1,1-二溴烯烃和双胍有效的铜催化合成取代的2,4-二氨基-1,3,5-三嗪。该反应以中等至良好的产率进行,并且可以耐受含有官能团(例如腈,醚和卤素)的烷基,杂环或芳基取代的1,1-二溴代烯烃。单取代至四取代的双胍也提供了所需的产物。
