The intramolecular oxidativecyclization of N-(2-formylphenyl)amides has been realized through an oxidative C(sp2)–O(sp2) bond-forming reaction between an aldehyde carbon and amide oxygen. This new strategy, which uses tert-butyl hydroperoxide (TBHP) as an oxidant and CoCl2 as the catalyst, allows for the efficient Co-catalyzed synthesis of useful benzoxazin-4-one derivatives and features readily available

Abstract The synthesis of new eight‐membered cycle dibenzo[b,f][1,5]‐diazocine‐6‐(5H)‐one derivatives 11, 12 was developed. The key step in this synthesis was the intramolecular cyclization of the amino aldehyde precursors 9,10 obtained by a selective reduction of the nitro benzamides 7, 8.
