Description
本发明涉及新的光学活性膦噁唑啉配体、其制备方法、含有这种新配体的金属络合物以及这种络合物,或配体与金属盐或络合物的组合作为非对称合成的催化剂的用途。
显示出独特反应性和高对映选择性的新型催化体系的开发在科学和技术中具有极为重要的意义。许多药物、农业化学品、香料和食品添加剂的活性都与特定的对映体有关。因此生产对映体纯化合物的能力是很重要的。已经开发了许多获得这种对映体纯化合物的方法,包括从天然存在的手性物质的光学拆开和结构改性到使用合成手性催化剂和酶的不对称催化。已经发现不对称催化即使不是生产对映体纯化合物的最有效的方法,也是最有效的方法之一,因为使用少量的手性催化剂就可生产大量的手性化合物。
在开发手性催化剂中一类起重要作用的配体是不对称膦配体。自从DIPAMP配体用于生产L-Dopa以来虽然已经合成了1000多种手性二膦配体,但其中只有少数配体具有工业应用的效率和选择性。所用的一些最熟知的膦配体包括BINAP,BPPM,DEGPHOS,DIOP,Chiraphos,Skewphos,Duphos和BPE,所有这些缩写均描述于例如WO 97/47633的注解中,并并入本文作为参考。然而,这些配体有其缺点,因而对于所有应用并不理想。
因此,仍然需要开发具有高度对映体选择性并能进行所需反应获得高收率的新型手性催化剂。
