A simple and environmentally friendly method is developed for the synthesis of substituted indoles from commercially available aryl hydrazines and cyclic enol ethers with Montmorillonite-K10 as a heterogeneous catalyst. The catalyst is non-toxic, inexpensive and recyclable and the process is clean, high yielding and operationally simple.
开发了一种简单且环保的方法,以蒙脱土-K10为多相催化剂,由市售的芳基肼和环状烯醇醚合成取代的吲哚。该催化剂是无毒的,廉价的和可回收的,并且该方法是清洁的,高产率的并且操作简单。
