Abstract

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-halobenzonit-rile, and (iii) a three step sequence via a 2- halobenzamide and a tosylate or chloride. Phosphinooxazolines containing stereogenic ...
