A mild and efficient method for the synthesis of 2‐aminobenzoxazoles through a Cu‐catalyzed electrophilicamination of benzoxazole derivatives with O‐benzoyl hydroxylamines by direct magnesation has been developed.
An efficient single step process for the construction of pharmaceutically relevant substituted aminobenzoxazoles have been described in this report. Various electrodes and electrolytes combinations have been carried out to harvest optimum coupling results. The presented CN bond formation reaction methodology has applied for the synthesis of biologically active compounds. This methodology saves reaction
