The aim is to explore a palladium-catalyzed reaction for synthesizing indole and carbazole derivatives.
Utilized -tosyl-2-(arylethynyl)anilines and 2-ethynylaziridines in the reaction.
Conducted the reaction at 80 °C.
Isolated carbazole derivatives through intermediates.
Successfully synthesized carbazole derivatives from 2-alkynylanilines.
Formation of 3-allenylindole intermediates observed during the reaction.
Abstract
-tosyl-2-(arylethynyl)anilines with 2-ethynylaziridines under the same catalysis conditions at 80 °C gives carbazole derivatives via the 3-allenylindole intermediates.
