A general regio-and stereoselective synthesis of 3, 3-diarylacrylamides is reported. Palladium-catalyzed coupling reactions of propiolamides with aryl halides provide arylpropiolamides. A subsequent hydroarylation reaction of these arylpropiolamides with aryl halides, catalytic palladium, an amine base, and formic acid in refluxing ethyl acetate provides 3, 3-diarylacrylamides regio-and stereoselectively. The unique stereo-and ...
