Puttappa, Sujit Kumar SarkarA facile one-pot protocol for the synthesis of substituted dibenzoxazepinones and pyridobenzoxazepinones from commercially available aryl/heteroaryl halides and amino phenols using octacarbonyldicobalt (Co2(CO)8) as an effective metal carbonyl source has been demonstrated. This method proceeds via the sequential coupling of aryl/heteroaryl halides with aminophenol by amidation and intramolecular cyclization to give dibenzoxazepinones/pyridobenzoxazepinones.
