An efficient one-pot synthesis of highly crowded tetrasubstituted tri(indolyl)methanes has been achieved through the addition/substitution sequence of 3-acetylindoles and indoles under mild conditions. The key to the success was improving the reactivity of 3-acetylindoles by rationally installing the N-protecting groups. The salient features including easily accessible and low-cost starting materials, board substrate scope, simple operation and structurally useful products make this approach particularly attractive.
