An efficient and convenient cobalt-catalyzed ortho-C(sp(2))-H amidation of benzaldehydes employing dioxazolones as the aminating reagent has been developed. The key feature of this protocol is the use of green and economic earth-abundant metals cobalt as the catalyst with the p-chloroaniline as the transient directing group. Further application of our approach was demonstrated by the synthesis of C1r serine protease inhibitor 45 and elastase inhibitor 49.
