摘要:
吡咯并[2,1- c ] [1,2,4]苯并三嗪(3)和4-氧代-4 H-吡咯并[2,1- c ] [1,4]苯并嗪(6)的反应性对典型的亲电试剂进行了研究,并将其与吡咯并[1,2- a ]喹喔啉(2)进行了比较。在所有三种化合物中,优选的取代位点是位置1;在化合物(2)和(3)中,C-3是取代的第二受欢迎的位置,但对于化合物(6),它是位置2。实验确定的卤化位点与分子轨道预测的位点相同计算。

Intramolecular N-arylation of pyrrole and indole carboxamides and carboxylates linked with a pendant haloarene by Cu-catalyzed reactions to synthesize pyrrole and indole quinoxalinone and oxazinone derivatives is reported. The ring closure reactions were carried out by conventional heating and MW irradiation. The use of conventional heating affords moderate to good yields of the quinoxalinone and oxazinone
