An efficient cobalt-catalyzed approach for synthesis of benzoxazoles from 2-aminophenol and aldehydes
摘要
The cobalt-catalysed approach has been developed for the synthesis of benzoxazoles under aerobic conditions. The easily available substrates, such as 2-aminophenols and aldehydes, studied for the synthesis of benzoxazole products and afforded with good tolerance of functional groups. The synthesised products were obtained in good yields under additive-free and ligand-free reaction conditions.
