A facile one-pot domino reaction for the stereoselectivesynthesis of acryl derivatives has been reported using alkaline earth catalyst [Ca(OTf)2]. Initially aryl amine reacts with ethyl propiolate to form β-enamino ester which further reacts with aryl aldehyde and indole in the presence of Ca(OTf)2 to give indolyl acrylates. It is interesting to note that in the absence of indole the reaction leads
