  aldehydes, and malononitrile in polyethylene glycol. The reagent system (PEG solvent plus catalyst) could be recycled up to 5 times for reaction with the same aldehyde and it was used also with at least three different aldehydes successively. This multi-component reaction (MCR) occurs first through Knoevenagel condensation followed by Michael addition of indole.

  The condensation of indole, benzaldehyde, and malononitrile was relatively rigorous compared with other Yonemitsu type reaction. We described a strategy using catalytic amount of choline chloride-dimethylurea deep eutectic salts as cheap and safe accelerator. We also found that introducing right amount of water in reaction system was crucial. This method tolerates variations in all three components to get desired 3-substituted indoles in satisfactory yields.

  A green one-pot multicomponent reaction for the synthesis of 3-indole derivatives was developed via L-proline-catalyzed condensation between indoles, aldehydes, and malononitrile. The process was carried out in ethanol at room temperature, and the desired products were obtained in good to excellent yields of up to 98%. Pyrrole as the nucleophile and 2,2,2-trifluoroacetophenone as the electrophile can also work in this transformation. The salient features of this protocol were environmental friendliness, simplicity of the procedure, ready accessibility of the catalyst, high yield, and mild reaction conditions.
