Palladium-catalyzed synthesis of 5- and 5,7-substituted indole derivatives

Yang, Shyh-Chyun,Chung, Wen-Hung

, p. 897 - 904 (2007/10/03)

The reaction of IPy2BF4 with anilines give the corresponding 2- iodoanilines regioselectively in high yields. N-Allyl-2-iodoanilines undergo cyclization to give 5- and 5,7-substituted indole derivatives in the presence of palladium catalysts and bases. The procedure do not require protective groups on nitrogen.
