Description
Details of the synthesis of three stereoisomers of erythrochelin, a hydroxamate-type tetrapeptide siderophore produced by Saccharopolyspora erythraea, were described. Both enantiomers of protected δ-N-hydroxyornithine were used as key intermediates in the synthesis of stereoisomers of erythrochelin containing a (3S,6S)-3,6-disubstituted-2,5-diketopiperazine ring. From comparisons of 1H and 13C NMR spectra, neither of stereoisomers provided a match for the erythrochelin spectral data, and the absolute configuration of erythrochelin was unambiguously reconfirmed to be (R,R,S,S).
