Diels-Alder reactions of the (1H-indol-3-yl)-enacetamides and -endiacetamides 1a - d with some carbodienophiles and 4-phenyl-3H-1,2,4-triazole-3,5(4H)-dione give rise to the novel amino-functionalized carbazoles 4 - 6 and 8 (Scheme 3).Ethenetetracarbonitrile reacts with 1b to furnish the Michael-type adduct 7 (Scheme 3).Structural aspects of the starting materials 1, which exhibit above all 3-vinyl-1H-indole reactivity, are discussed with regard to the prediction of a Diels-Alder process.
Indoles and Indole Alkaloids, XXI. - Preparation of 4-(Acetylamino)-1,2,3,9a-tetrahydrocarbazole Derivatives by Cycloadditions of 3-Indolyl-enimides and -enamides

Treatment of the oximes of the 3-acetylindoles 1 and 5 with acetic anhydride in pyridine results in the formation of the enimides 2 and 7, which slowly undergo cycloadditions with acrolein and derivatives of acrylic acid to form 3 and 10, respectively.Com
