A concise synthesis of indolic enamides coscinamide A, coscinamide B, and the brominated tryptamine derivative igzamide is described. Both E- and Z-isomers of these natural compounds were obtained during the thermally assisted dehydration reaction and were tested for antitumor activity. Coscinamide B was found to possess antitumor activity against DU145 with an IC50 of 7.6 mu g/mL. (C) 2009 Elsevier Ltd. All rights reserved.
