从异喹啉-3-胺开始已详细阐述了新的2,3-二芳基-3 H-吡咯并[2,3- c ]异喹啉衍生物的合成。Buchwald–Hartwig芳基化和随后在位置4的碘化反应得到3-芳基氨基-4-碘异喹啉。这些化合物与一些选定的乙炔进行Sonogashira交叉偶联反应,所得的偶联产物在氟化四丁基铵的存在下进行环化,得到标题衍生物。
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。

A novel cascade C–H functionalization/cyclizationreaction of N-arylpyridin-2-amines with α,β-unsaturated aldehydes has been developed under rhodium catalysis, affording dihydroquinolinone derivatives in moderate to excellent yields. A plausible mechanism of dual catalytic cycles by rhodium(III) catalysis is also proposed.
Isoquinolin-3-amines bearing an alkyl group or hydrogen atom in position 4 easily underwent Buchwald-Hartwigcoupling reactions with various substituted aryl halides. Investigation of the selected new derivatives with fluorescent spectroscopy revealed that the reaction products have similar photophysical properties to those of isoquinolin-3-amine except the N-(nitrophenyl) derivatives, which emit negligible

Disclosed are a novel amino anthracene derivative and an organic electro-luminescence device using the same. More specifically, the disclosed amino anthracene derivative has a core (e.g., indenoanthracene core) of an anthracene moiety (with a high device characteristic) linked to a fluorene moiety (with a high fluorescence characteristic), in which in the core is substituted with at least one amine group represented by Formula 2 and the disclosed organic electro-luminescence device uses the amino anthracene derivative as a light emitting layer material so as to be enhanced in efficiency, operating voltage, and life span.

Condensation of 2-cyanomethyl benzaldehydes 1 with 2 (ammonia, primary or secondary amines) carried out in the presence of a catalytic amount of trifluoroacetic acid, afforded 3aminoisoquinolines 3. In the case of primary amines azomethines 4 were formed at first, they dissociated and subsequently yielded 3 in a rather slow process.
