The preparation of enantiomerically pure liginds which contain both an oxazoline group and an additional sulfur or phosphorus donor atom are described. Methyithiomethyl, o-thioanisyl and thienyl oxazolines have been prepared in one step, and o-diphenylphosphinophenyl oxazolines have been prepared in two steps in good yields from commercially available starting materials.
