Palladium-Catalyzed Regioselective 2-Carbethoxyethylation of 1H?￠????Indoles By C-H Activation: One-Step Synthesis of Ethyl 2-(1H-Indol-2-Yl) Acetates

摘要

An efficient and convenient method was developed for the one-step synthesis of various substituted ethyl 2-(1H-indol-2-yl) acetates via a palladium-catalyzed regioselective cascade C-H activation reaction. Importantly, this practical approach can be carried out with readily accessible starting materials and exhibits excellent functional group compatibility.
