A new type of transesterification between aryl, heteroaryl, alkyl N-heteroarene-2-carboxylates and various aldehydes by C–H and C–O bondactivations has been developed for the synthesis of versatile carboxylates. A possible mechanism containing oxidative addition of acyl–O bond in parent ester and radical cleavage of sp2 C–Hbond in aldehyde is proposed.

AbstractAn oxidative cross‐coupling reaction between aldehydes and sulfoximines involving dual CH/NH functionalization has been developed. This reaction process is facilitated by a simple copper catalyst (1 mol% loading) and tert‐butyl hydroperoxide (TBHP) as the oxidant and proceeds under mild reaction conditions to afford a series of valuable N‐acylated sulfoximine derivatives in excellent yields.
