An efficient Michael addition of indoles to electron‐deficient olefins under solvent‐ and catalyst‐free condition afforded biologically important 3‐substituted indole derivatives in good to excellent yields was reported. The acidic NH proton of indole plays a key role in Michael addition of indoles to electron‐deficient olefins. This very simple procedure provides an efficient and clean process for the synthesis of indole derivatives. J. Heterocyclic Chem., (2011).
