synthesized. The electrocatalytic process was found to be advantageous in terms of selectivity and yields compared to classic chemical base catalysis, and includes a remarkable mechanistic feature that is promising for the further development of 2-amino-4H-chromene chemistry. The application of this convenient electrocatalyticmulticomponent method to the formation of medicinallyrelevant 2-amino-4H-chromenes

efficient and environmentally benign procedure for the reactions of three components condensation of salicylaldehyde and two different CH acids to give 2‐amino‐4H‐chromenes catalyzed by a series of basic‐functionalized ionicliquids was reported. The most possible reaction pathway was proposed for the first time by performing density functional theory (DFT) calculations. Both cation and anion of [Bmim]OH
