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.

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。

A novel synthetic route to the indoloquinoline core of the alkaloid isocryptolepine involving an unprecedented PPA-mediated reaction of 2-(2-aminophenyl)indenes with nitroalkenes is discovered.
2‐(2‐Isocyanophenyl)‐1H‐indoles, a class of functionalized isocyanides containing both aromatic C−H and indolo N−H functionalities, are first applied in selective imidoylative annulation reactions. Scaffolds of 6‐aryl 11H‐indolo[3,2‐c]quinoline and 6‐aryl indolo[1,2‐c]quinazoline, both of which are of biological importance, are obtained selectively through capturing the imidoyl radical or imidoyl palladium
2-(2-异氰基苯基)-1 H-吲哚是一类同时具有芳族CH和吲哚N-H官能度的官能化异氰化物,首先用于选择性的酰亚胺化环化反应中。通过捕获亚氨基自由基或亚氨基钯选择性地获得具有生物重要性的6-芳基11 H-吲哚并[3,2- c ]喹啉和6-芳基吲哚并[1,2- c ]喹唑啉的支架。通过CH键和NH键的中间体。
