In the presence of FeCl3 as catalyst the one-pot domino reactions of arylamines, methyl propiolate, aromatic aldehydes, and indole in ethanol at room temperature proceeded smoothly to give methyl 2-(1H-indol-3-yl)arylmethyl-3-arylamino)acrylates in good yields. H-1 NMR spectra and single crystal structures indicated that (Z)-acrylates were stereoselectively formed in the reactions. (C) 2012 Elsevier Ltd. All rights reserved.
