A simple and convenient method for the N-formylation of primary and secondary amines including amino acids has been developed utilizing formamide and sodium methoxide in moderate to excellent yield. This reagent is also utilized for one pot conversion of compounds having amino esters to N-formyl amides.

Moreover, it delinates a ligand- and additive-free amine oxidation process mediated by a low-cost metal salt with oxygen from air taking on the role of both the terminal oxidant and as part of the formylation reagent, which is unprecedented in copper catalysis. It also offers the first synthetic method that can selectively generate α-amino radical species as reactive intermediates from α-silylamines under
