Synthesis of new optically active sulfoxides with chelating properties
Access to enantiomerically pure 2-pyridinylmethyl sulfoxides and β-imino sulfoxides was sought.The latter were obtained in tautomeric mixtures with their enamines by condensation of optically active β-keto sulfoxides with primary amines. 2-Pyridinylmethyl

Synthesis of Enantiomerically Enriched α-Sulfenylated Ketones and Aldehydes
α-Sulfenylated carbonyl compounds are prepared by the reaction of imines of aldehydes and ketones containing α-hydrogens with disulfides via the metalloenamines.With (R)-α-phenylethylamine as chiral auxiliary, enantiomeric excess of 13-51percent are obser
