A practical and cost-effective synthetic method of P-chiral diarylalkyl, aryldialkyl, and triaryl phosphine oxides by using readily available chiral diphenyl-2-pyrrolidinemethanol as the auxiliary is developed. The long-standing racemization issue during solvolysis has been addressed and well controlled by employing a suitable solvent, a low reaction temperature, and an appropriate reaction time.
的一种实用和符合成本效益的合成方法P -手性二芳基烷基,aryldialkyl,和由作为辅助开发使用容易获得的手性二苯基-2-吡咯烷甲醇三芳基膦氧化物。通过使用合适的溶剂,低的反应温度和合适的反应时间,溶剂分解过程中长期存在的外消旋问题已经得到解决和控制。
