纳米催化剂和绿色化学路线(机械化学)的结合被用于生成一系列取代的1,1-双(2-苯基-3-吲哚基)乙烯衍生物(4a-e),这些衍生物是通过使各种2-芳基吲哚反应而合成的(1a–e)和无水乙醇中的乙酰氯,有或没有ZnO纳米作为催化剂,通过两种方法进行,即经典方法和绿色无溶剂方法。就短的反应时间和温和的反应条件以及催化剂的可再利用性而言,ZnO纳米颗粒的使用优于不存在催化剂。根据其元素和光谱数据(IR,质子磁共振,13 C NMR和质量)对所有合成的化合物进行表征。
2,2'-Diphenyl-3,3'-diindolylethylene (DPDIE) derivatives 3a-g were regioselectively prepared in one pot from indoles 1a-g in the presence of Lewis acids and were subsequently evaluated for cytotoxic activity against human leukemic cell lines, U937 and K562. The most potent compound 3g exhibited IC50 of 13.0-17.0 mu M. (C) 2011 Elsevier Ltd. All rights reserved.

A combination of nanocatalyst and green chemical route (mechanochemistry) was used to generate a series of substituted 1,1‐bis(2‐phenyl‐3‐indolyl)ethylene derivatives (4a–e) that were synthesized by reacting various 2‐arylindoles (1a–e) and acetyl chloride in absolute alcohol with or without ZnO nano as catalyst via two approaches, that is, classical and green solvent‐free route. The use of ZnO nano
