由市售或合成的氨基醇制备一系列对映体纯的2- [2-(二芳基膦基)芳基]-恶唑啉。对于恶唑啉的形成,采用了三种程序:(i)与2-卤代苯甲酸一锅缩合,(ii)ZnCl 2与2-卤代苯甲腈-苯胺催化缩合,和(iii)通过2-卤代苯甲酰胺的三步顺序和甲苯磺酸盐或氯化物。通过非对映选择性亲核取代Ar 1 Ar 2 PC1的卤化物或通过LiPAr 1 Ar 2亲核芳族取代制备含有立体异构磷的膦恶唑啉。另外,制备了硫和硒类似物。

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 phosphorus were prepared by either diastereoselective nucleophilicsubstitution of halogenide
