摘要本文研究了4-甲氧基吲哚啉衍生物的硝化反应。我们现在报告一个简单的方法,硝化采用粘土铜在胺的存在下,提供了显着的改善方面的产率和区域选择性,和一个更有利的异构体比例的产品在温和的条件下获得。因此,一个有用的方法制备的光不稳定的L-谷氨酸盐衍生物的同时建立。
Abstract The present work investigates the nitration of 4-methoxy indoline derivative with different reagents and optimized conditions. We now report a simple methodology for nitration employing claycop in the presence of amine, which offers significant improvement with regard to the yield and regioselectivity, and a much more favorable isomeric ratio of products was obtained under mild conditions. Therefore, a useful method for preparation of a photolabile L-glutamate derivative was concurrently established.
