synthesis and conformational analysis of mono- and disubstituted ferrocene bioconjugates bearing dipeptide chains (Boc-AA-AA-Fn-X, AA=Gly, l-Ala, l-Val). The conformational preferences of novel aminoferrocene derived conjugates with X=H, as well as their 1-acetyl analogues (X=COMe), were investigated by spectroscopic techniques (IR, NMR and CD) and corroborated by DFT calculations.
