straightforward L-proline catalyzedone-potsynthesis of a series of biologically relevant gem-(β-dicarbonyl)arylmethanes has been developed via a three-component reaction between indoles, aldehydes and C–H activated acids by grinding them together under solvent-free conditions at room temperature. Mild reaction conditions, high atom-economy, good yields, and eco-friendliness are some of the salient

obtained from a three-component reaction of indole, aldehyde, and N,N-dimethylbarbituric acid, undergo an elimination-addition reaction with another indole molecule or heterocyclic nucleophile giving unsymmetrical diindolylmethanes or heterocyclic(indolyl)alkanes in the absence of a catalyst.
