  Synthesis and in vitro evaluation of 4-trichloromethylpyrrolo[1,2-a]quinoxalines as new antiplasmodial agents

  摘要：

  Thanks to a preliminary in vitro screening of several CCl3-substituted-nitrogen containing heterocycles belonging to our chemical library, the 2-trichloromethylquinoxaline scaffold appeared to be of potential interest for developing new antiplasmodial agents. Then, combining these experimental results to the antimalarial properties reported for various pyrrolo[1,2-a]quinoxaline derivatives, an original series of fifteen 7-substituted-4-trichoromethylpyrrolo[1,2-a]quinoxalines was synthesized in a 4 to 5 reaction steps pathway. All molecules were evaluated in vitro toward both their antiplasmodial activity on the K1 multi-resistant Plasmodium falciparum strain and their cytotoxicity on the HepG2 human cell line. Thus, 3 hit molecules were identified, displaying IC50 values in the micromolar range and low cytotoxicity values, reaching good selectivity indexes, in comparison with the reference drugs chloroquine and doxycycline. Structure-activity relationship studies showed that the pyrrolo[1,2-a]quinoxaline scaffold can support selective antiplasmodial activity when substituted at position 4 by a CCl3 group. However, substitution at position 7 of the same scaffold is neither beneficial for cytotoxicity nor favourable for the solubility in the biological media.

  Methods to afford pyrrolo[1,2-a]quinoxalines often require the use of prefunctionalized aniline precursors, transition metals, and/or harsh conditions. Herein we describe a simple coupling of 1-(2-nitroaryl)pyrroles and arylacetic acids, in the presence of elemental sulfur, to furnish the fused heterocycles in good yields. The conditions are compatible with many functionalities including ester, nitrile

  C–H carbonylative reaction of N-(2-(1H-indol-1-yl)phenyl)picolinamides for the synthesis of (NH)-indolo[1,2-a]quinoxalin-6(5H)-one skeletons has been developed. Using benzene-1,3,5-triyl triformate (TFBen) as the CO source and picolinamide as the traceless directing group, various free (NH)-indolo[1,2-a]quinoxalin-6(5H)-ones were obtained in good yields (up to 88%). Additionally, a series of product derivatizations

  Catalyst‐controlled chemodivergent annulation between o‐indolo anilines and diazo compounds has explored for the synthesis of indolo‐fused diazepine and quinoxaline. Under the Rh(III) catalyst, reaction proceeded through the free amine assisted C2−H activation followed by amidation leading to the diazepino[1,7‐a]indole in a highly selective manner. While with Ru(II) catalyst, reaction involves formation

  在邻吲哚苯胺和重氮化合物之间进行催化剂控制的化学发散环化反应已被研究用于合成吲哚稠合的二氮杂and和喹喔啉。在Rh（III）催化剂下，反应通过游离胺辅助的C2-H活化进行，然后进行酰胺化反应，从而以高度选择性的方式生成重氮庚并[1,7- a ]吲哚。当使用Ru（II）催化剂时，反应涉及形成Ru-卡宾配合物，然后插入-NH 2基团，并通过金属茂型反应进行级联环化，通过β-氢化物消除作用制得吲哚[1,2- a]。以喹喔啉为主要产品。该策略指导模块化方法构建独特的吲哚并结合的二氮杂/喹喔啉以及吡咯并并的二氮杂/喹喔啉骨架，并具有极高的产率。
