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
