Carbazoles via AuCl3-Catalyzed Cyclization of 1-(Indol-2-yl)-3-alkyn-1-ols
摘要:
AuCl3-catalyzed reaction of 1-(indol-2-yl)-3-alkyn-1-ols occurred smoothly in toluene at room temperature to form a benzene ring leading to a series of carbazole derivatives efficiently. A possible mechanism has been proposed for the formation of carbazoles.
