facile synthesis of highly symmetrical tetrasubstituted pyrazines through simple aerial oxidation of β-keto γ-amino esters is reported. The scope of the reaction was examined by use of various amino acid side-chain functional groups and peptides. The mild and efficient transformation of β-keto γ-amino esters into pyrazines may serve as an attractive strategy for self-dimerization of peptides.
