Abstract

A series of novel N- meta-ferrocenyl benzoyl dipeptide esters ( 2– 5) have been prepared by coupling meta-ferrocenyl benzoic acid ( 1) to the dipeptide ethyl esters using the conventional 1,3-dicyclohexylcarbodiimide (DCC), 1-hydroxybenzotriazole (HOBt) protocol. The dipeptides employed were GlyGly(OEt) ( 2), GlyAla(OEt) ( 3), GlyLeu(OEt) ( 4) and GlyPhe(OEt) ( 5). The compounds were fully characterized by a range of NMR spectroscopic techniques and by mass spectrometry (MALDI-MS, ESI-MS).
