Peptide esters coordinated in a chelate fashion as in 1 (M = Rh, R = Me) may be extended on the amino ends by reaction with α‐amino acid esters in the presence of base. In the case of L ‐leucine methyl ester the resulting tripeptide ester can be cleaved from the metal center with virtually no racemization. The organometallic reagent [{(C 5 Me 5 )RhCl 2 } 2 ] can be recovered.
