Synthesis of benzoxazoles via an iron-catalyzed domino C-N/C-O cross-coupling reaction

摘要

An eco-friendly and efficient method has been developed for the synthesis of 2-arylbenzoxazoles via a domino iron-catalyzed C-N/C-O cross-coupling reaction. Some of the issues typically encountered during the synthesis of 2-arylbenzoxazoles in the presence of palladium and copper catalysts, including poor substrate scope and long reaction times have been addressed using this newly developed ironcatalyzed method.
