6-甲基-6 H-吲哚并[3,2- c ]异喹啉和6-甲基-6 H-吲哚并[2,3- c ]异喹啉的合成:隐谷碱系列的两种新的非天然异喹啉异构体
摘要:
11 H-吲哚并[3,2- c ]异喹啉通过选择性的布赫瓦尔德-哈特维格反应,然后经钯催化的涉及C(sp 2)的分子内直接芳基化反应,从4-溴异喹啉和2-溴苯胺开始分两步合成。H激活。7 H-吲哚并[2,3- c ]异喹啉的合成是通过Suzuki反应与从4-溴异喹啉和{2-[(2,2-二甲基丙酰基)氨基]苯基开始的分子内氮插入反应的结合而实现的}硼酸。四环骨架的选择性甲基化产生标题化合物6-甲基-6 H-吲哚并[3,2- c ]异喹啉和6-甲基-6 H-吲哚并[2,3-c ]异喹啉,以前在文献中从未描述过。
Synthesis of pyrido[1,2-a]benzimidazoles by photo-stimulated C–N bond formation via SRN1 reactions
摘要:
The photo-stimulated cyclization of 2-(2-halophenylamino)pyridines in liquid ammonia afforded pyrido [1,2-a]benzimidazoles via S(RN)1 mediated C-N bond forming reactions in moderate to excellent yields (58-94%). This general synthetic strategy was also extended to a 2-(2-bromophenylamino)pyrazine to give pyrazino[1,2-a]benzimidazole. Attempts to employ this reaction using N-(2-chlorophenyl)-3-isoquinolinamine, however, resulted in C-C bond formation generating 7H-indolo[2,3-c]isoquinoline. (C) 2013 Elsevier Ltd.
