Abstract

A range of ferrocenylimines derived from ferrocenecarboxaldehyde and the a-amino acids (S)-alanine, (S)-2-aminobutyric acid, (S)-norvaline, (R)-2-phenylglycine, (S)-phenylalanine, O-benzyl (S)-serine, and (S)-tryptophan can be cyclised stereoselectively to afford either the corresponding cis- or trans-2-ferrocenyl-3-pivaloyl-4-alkyl-1,3-oxazolidin-5-ones. The cyclisation reaction shows marked temperature dependence, giving rise preferentially to the trans-oxazolidinone under kinetic control (-78 degrees C) and the thermodynamic cis-oxazolidinone at -15 degrees C to rt.
