  Water Assisted and Choline Chloride-Dimethylurea Deep Eutectic Salts as Catalyst towards the Attractive Reaction of Indole, Benzaldehyde, and Malononitrile

  摘要：

  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.

  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.
