Abstract
A series of N - para -ferrocenyl benzoyl dipeptide esters 2 – 5 were prepared by coupling para -ferrocenyl benzoic acid ( 1 ) to the dipeptide ethyl esters using the conventional 1,3-dicyclohexylcarbodiimide (DCC), 1-hydroxybenzotriazole (HOBt) protocol. The dipeptides employed in the synthesis were Ala-Gly(OEt) ( 2 ), Ala-Ala(OEt) ( 3 ), Ala-Leu(OEt) ( 4 ) and Ala-Phe(OEt) ( 5 ). The compounds were fully characterized by a range of NMR spectroscopic techniques, electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS). In addition the X-ray crystal structure of the l -alanine-glycine derivative 2 has been determined.
