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。

Indolo[3,2-c]quinolines are pharmacologically attractive class of heterocyclic compounds. The method of their synthesis, based on transformation of furfural, which is a large-scale product of treatment of biomass including agricultural and forestry wastes, has been developed. This method was utilized for the total synthesis of antimalarial alkaloid isocryptolepine and its derivatives.
吲哚并[3,2- c ]喹啉是一类具有药理吸引力的杂环化合物。它们的合成方法,基于变换糠醛已开发出大规模处理包括农业和林业废物在内的生物质的产品。该方法用于抗疟生物碱的全合成异隐油平 及其衍生物。
