Palladium-catalyzed functionalization of 5- and 7-azaindoles
摘要:
Palladium-catalyzed functionalization at the 2-position of various 5- and 7-azaindoles was performed by Suzuki, Heck, and Stille reactions. The 2-substituted azaindoles were obtained with 5% Pd(OAc)(2), LiCl, and KOAc in DMF at 110 degrees C with moderate to high yields. (C) 2000 Elsevier Science Ltd. All rights reserved.
