substituent at the 2-position of mono-substituted quinoxalines in the synthesis of di-substituted quinoxaline derivatives via nucleophilic substitution reactions, is reported. Di-substituted quinoxalines bearing aryl-alky, aryl-aryl, aryl-heteroaryl, aryl-alkynyl, and amino-alkyl substituents were prepared in moderate to good yields. 2-Monosubstituted quinoxalines bearing a phenyl and butyl substituent reacted
报道了在通过亲核取代反应合成二取代喹喔啉衍生物中单取代喹喔啉的2-位上取代基的作用的研究。制备具有中等至良好产率的带有芳基-烷基,芳基-芳基,芳基-杂芳基,芳基-炔基和氨基-烷基取代基的二取代喹喔啉。带有苯基和丁基取代基的2-单取代喹喔啉容易与烷基,芳基,杂芳基和炔基核亲核素反应,得到二取代喹喔啉。带有胺和炔基取代基的2-单取代喹喔啉仅与烷基亲核试剂反应。在大气O 2中发生氧化重整化,得到2,3-二取代的喹喔啉产物。
