of glycine–amino acid was synthesized by coupling of substituted 2-(aminomethyl)malononitrile as a C-terminal glycine unit and N-terminal amine using CsOAc and O2 in an aqueous solution. This is a coupling reagent-free and catalyst-free peptide synthesis via oxidative amide bond formation. Various tripeptides and tetrapeptides were synthesized efficiently and the sulfide moiety is inert even under

丙二腈作为C末端甘
氨酸单元和N末端胺而合成的。这是通过氧化酰胺键形成的无偶联试剂和无催化剂的肽合成。有效地合成了各种三肽和四肽,并且即使在
氧气气氛下,
硫化物部分也是惰性的。
