A novel approach towards the synthesis of α-ketoamides using a TBHP/I2-promoted tandem reaction of amines with β-diketones via CâC bond cleavage has been developed. This one-pot reaction proceeded well under metal-free conditions and generated the corresponding products with good yields.

Single‐step amination: The N‐iodosuccinimide (NIS)‐catalyzed amidation of acetophenone derivatives by using tert‐butylhydroperoxide (TBHP) as an oxidant is presented. A variety of acetyl derivatives of heterocyclic compounds were easily converted to their corresponding ketoamides under these conditions. A new, NIS‐catalyzed amination of propiophenone and its derivatives in the presence of TBHP to furnish
Cu(OAc)2 and acids promoted the oxidative cleavage of α-aminocarbonyl compounds with amines: efficient and selective synthesis of 2-t-amino-2-imino-carbonyl and 2-amino-2-oxocarbonyl
method for the synthesis of 2-t-amino-2-imino-carbonyl (C) and 2-amino-2-oxocarbonyl (D) compounds has been discovered through a copper-promoted oxidating amidation reactions between α-amino -carbonyl compounds and amines. Promoted by the crucial copper species, perfect selectivity and good to excellent yields could be achieved. This transformation is achieved through CN bond oxidative cleavage and formation
