Indolo[3,2-c]quinolones have been efficiently synthesized via an acid-mediated, one-pot, three-component condensation of arylhydrazines, o-aminoacetophenones, and triazines or nitriles. The synthetic application of this method is showcased by the concise synthesis of isocryptolepine alkaloid and a series of its synthetic analogues with demonstrated cancer cell antiproliferative activities.
吲哚并[3,2- c ]喹诺酮已通过芳基肼,邻氨基苯乙酮和三嗪或腈的酸介导的一锅三组分缩合反应得到了有效合成。该方法的合成应用通过异隐油菜碱生物碱及其一系列具有证明的癌细胞抗增殖活性的合成类似物的简明合成得以展示。

acid-mediated one-pot three-component synthesis of indoloquinoline scaffold is developed. This improved version of the process involves electrophilically activated nitroalkanes for the installation of strategic C–C and C–N bonds and ring C assembly. This modification allows the elimination of unnecessary solvent change operations and all steps are carried out in a true, uninterrupted one-pot manner. A
开发了二代多聚磷酸介导的一锅三组分合成吲哚喹啉支架。该工艺的改进版本涉及用于安装战略 C-C 和 C-N 键和环 C 组装的亲电活化硝基烷烃。这种修改可以消除不必要的溶剂更换操作,并且所有步骤都以真正的、不间断的一锅法进行。进一步的改进涉及原位安装邻氨基的可能性。该方法的合成应用通过简明合成异隐萜生物碱及其具有有效抗癌活性的合成类似物来展示。
