A general and efficient method has been developed for the synthesis of 3-aminoalkylated indoles by a three-componentcoupling of indoles, aldehydes, and amines in the presence of a catalytic amount of zwitterionic-type molten salt under solvent-free conditions. The non-hazardous experimental procedure, mild reaction conditions, and the reusability of the catalyst are the notable advantages of the present

A simple and highly efficient protocol for the one-pot synthesis of a series of 3-[(N-alkylanilino)(aryl)methyl]indoles has been developed based on low-cost and environmentally benign zirconium oxychloride octahydrate and copper chloride dihydrate catalysts via three-component condensation between indoles, aromatic aldehydes, and N-alkylanilines at room temperature under neat condition. Mild reaction
