A new strategy for the synthesis of biologically active quinoxalines by using versatile α-nitro epoxides as starting compounds has been developed. In addition, the in situ organocatalytic epoxidation of electron-poor nitro olefins followed by condensation with 1,2-phenylenediamines to provide quinoxalines in one pot has been demonstrated.
已经开发出一种使用多功能α-硝基环氧化物作为起始化合物合成具有生物活性的喹喔啉的新策略。此外,已经证明了缺电子硝基烯烃的原位有机催化环氧化,然后与 1,2-苯二胺缩合以在一锅中提供喹喔啉。
