Palladium-Catalyzed Synthesis of 2,3-Disubstituted 5-Azaindoles via Heteroannulation Reaction and of 2-Substituted 5-Azaindoles through Domino Sila-Sonogashira/5-Endo Cyclization
A general and efficient procedure for the synthesis of 2,3-disubstituted 5-azaindoles through the palladium-catalyzed heteroannulation of 4-acetamido-3-iodopyridines and diaryl-, dialkyl-, or arylalkylalkynes is described along with a study of the reaction regioselectivity. The preparation of 2-monosubstituted 5-azaindoles via sila-Sonogashira/5-endo cyclization is also reported. These methods allowed

spin-labeled charge acceptors to produce three-spin systems of "radical ion/biradical ion" type in X-irradiated alkane liquids. This opens the way to studyspin triads in experimental conditions, in which short-lived radical ion pairs are conventionally studied, thus offering optically detected techniques such as magneto-resonance OD ESR and level-crossing MARY spectroscopy. The structure of the synthesized
该贡献报告了一系列自旋标记的电荷受体的设计和合成,以在 X 辐照的烷烃液体中产生“自由基离子/双自由基离子”类型的三自旋系统。这为在实验条件下研究自旋三元组开辟了道路,其中传统上研究了短寿命的自由基离子对,从而提供了光学检测技术,如磁谐振 OD ESR 和水平交叉 MARY 光谱。合成的2-咪唑啉-1-氧基衍生物的结构为A-Sp-R,其中A为正或负电荷受体,R为稳定自由基,Sp为烃桥。这组 20 多种化合物代表了构建具有各种特性的实验性三自旋系统的便捷工具,例如具有“第三” 自旋引入自由基离子对的一个或另一个伙伴。双自由基离子中两个顺磁性碎片之间的交换耦合程度已被证明强烈依赖于自由基碎片 R 的类型和桥 Sp 的结构。结果,合成了一系列交换相互作用系统性降低的受体,并找到了观察低磁场效应的最佳系统。在最有利的情况下,来自自旋黑社会的 OD ESR 信号短至约。100 ns 已被注册为单个未解析的行。根据
