The invention provides new pyrrolo-nitrogenous heterocyclic derivatives represented by formula (I) or their salts, the preparation thereof, pharmaceutical compositions containing such derivatives and the use of such derivatives as therapeutic agents, especially as protein kinase inhibitors, wherein each substituent in formula (I) is same as defined in the description.
A new versatile method for the synthesis of supported mono and diphosphines on polypyrrole matrix is described, based on the protective borane complexation of the phosphorus atom. For the first time, the unknown alkylation of a diphosphine ethano bridge, was obtained with near yield close to 70%, leading to its derivative 8 bearing the polymerizable pyrrole group on a side chain. The different supported

reactions including nucleophilicsubstitution reactions. Song et al. have recently reported metal triflate catalyzed Friedel-Crafts alkylation of aromatic compounds with alkenes and alkynes in hydrophobic ILs. Also recently, we have demonstrated that ILs enhance pyrrole C–alkylation regioselectively at C2 position vianucleophilicsubstitution reaction. Further, our group reported the synthesis of chromane
CC键的形成——分子的基本组成部分是化学中最重要的化学现象。Friedel-Crafts 烷基化是 CC 键构建中的一种。通过傅-克烷基化对芳环进行烷基化已得到很好的证实。Friedel-Crafts 烷基化的分子内形式已成为快速构建许多碳杂环化合物的有效方法。然而,由于高反应性,发现某些稠环体系中的反应没有什么好处。此外,杂环往往是傅克反应的不良底物。在过去的十年中,离子液体(IL,图 1)在许多有机反应(包括亲核取代反应)中作为溶剂比传统有机溶剂具有巨大的潜力。宋等人。最近报道了金属三氟甲磺酸盐催化芳族化合物与疏水性离子液体中的烯烃和炔烃的傅克烷基化。同样最近,我们已经证明 ILs 通过亲核取代反应在 C2 位区域选择性地增强吡咯 C-烷基化。此外,我们小组报道了在 IL 中使用分子内 Friedel-Crafts 反应合成色烷衍生物。此外,由于催化剂更容易从反应介质中分离,并且可能在连续系统中利用催化剂,因此将
