enantiomerically pure aziridine-2-carboxylic acid menthol ester 13. Vanadium complexes of the chiral Schiff-base ligands prepared from the β-amino alcohols catalyze an efficient enantioselective sulfoxidation of alkyl aryl sulfides, while enantioselectivities as high as 96% ee can be observed in the sulfoxidation of benzyl aryl sulfides.
