Facile synthesis of benzo[4,5]furo[3,2-c]pyridines via palladium-catalyzed intramolecular Heck reaction
摘要:
The heating of 4-chloropyridine with 2-bromophenol in either neat or DME as solvent gives rise to 2-bromophenoxy pyridines, which were treated with Pd(OAc)(2) and various ligands to afford functionalized benzo[4,5]furo[3,2-c]pyridines. (C) 2009 Elsevier Ltd. All rights reserved.

Intramolecular arylation through direct C−H functionalisation is a convenient method for the formation of dibenzofurans. In the Pd‐mediated process, the use of quinoline ligands alleviates a number of the existing issues with the use of phosphineligands.
