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.

2,3-Disubstituted pyrrolo[2,3-b]pyridines were synthesized by palladium-catalyzed heteroannulation of 2-amino-3-iodopyridine derivatives and internal alkynes with Pd(OAc)2, LiCl, and KOAc in DMF. The 2-trimethylsilyl-3-methylpyrrolo[2,3-b]pyridine was transformed to 2-substituted-3-methylpyrrolo[2,3-b]pyridines.
