Synthesis of Ferrocenoyl L-Arginine Derivatives by Homogeneous Catalytic Carbonylation

Abstract Ferrocene–labeled arginine derivatives with different structures were synthesized via homogeneous catalytic carbonylation. Aminocarbonylation of iodoferrocene in the presence of L-arginine methyl ester or Nα-benzoyl-L-arginine ethyl ester as N-nucleophiles led to triacyl derivatives as the main products. The formation of diacyl compounds was also observed, but no monoacyl derivative could be isolated from the reaction mixture of iodoferrocene and L-arginine methyl ester.
