A series of enantiomerically pure 2-[2-(diarylphosphino)aryl]-oxazolines was prepared from commercially available or synthetic amino alcohols. For oxazoline formation three procedures were employed: (i) one pot condensation with a 2-halobenzoic acid (ii) ZnCl2 catalyzed condensation with a 2-halobenzonitrile, and (iii) a three step sequence via a 2-halobenzamide and a tosylate or chloride. Phosphinooxazolines containing stereogenic phosphorous were prepared by either diastereoselective nucleophilic substitution of halogenide of Ar1Ar2PCl or by nucleophilic aromatic substitution with LiPAr1Ar2. In addition, sulfur and selenium analogs were prepared.
