- Copper-catalyzed amidation of acids using formamides as the amine source
-
Copper-catalyzed amidation of acids with formamides or acetamide for the selective synthesis of amides with the aid of 1,4-diazabicyclo[2.2.2]octane as the ligand and tert-butyl hydroperoxide as the oxidant is presented. This method is highly compatible with a wide range of acids, including alkyl acids, aryl acids, α,β-unsaturated acids, and amino acids. A general and direct route for the synthesis of amides is described. The reaction involves the copper-catalyzed amidation of acids, wherein various formamides and an acetamide are used as the amine source. Importantly, this method represents a new strategy for the direct use of acids in the synthesis of amides. DABCO = 1,4-diazabicyclo[2.2.2]octane, TBHP = tert-butyl hydroperoxide. Copyright
