Description
技术领域
本发明涉及有机化学技术领域,具体涉及一种苯乙烯轴手性膦配体及其合成方法与应用。
背景技术
不对称合成是有机化学的前沿领域之一,它是通过在反应体系中使用手性试剂、手性溶剂、手性催化剂或其他不对称因素而得到某种具有光学活性的产物。1968年Knowles和Horner成功地合成了历史上第一个手性膦配体并将其铑配合物应用于催化不对称氢化反应。在其后的几十年中,已相继合成出数千个手性膦配体,这些手性膦配体在不对称合成中起着重要的作用,并实现了在医药农药、食品添加剂、昆虫信息素、香料等领域的广泛应用。
手性膦配体包括P-手性膦配体和C-手性膦配体。其中,P-手性配体由于其合成困难,在高温下构型容易翻转等因素,其合成和应用范围较为受限。 C-手性膦配体比P-手性膦配体的制备相对更容易,结构的变化性更大,因而得到了深入开发和广泛应用。常见的C-手性膦配体有酒石酸衍生的具有中心手性的DIOP类膦配体、联萘骨架的轴手性BINAP类膦配体和面手性的[2, 2]PHANEPHOS类膦配体等。近年来,轴手性苯乙烯型化合物的合成方法相继被报道,该类化合物拓展了轴手性化合物的类型,并展现出一定的应用价值。然而,合成含有这种轴手性苯乙烯结构的C-手性膦配体的报道却十分少见。 2016年,Zhenhua Gu等人利用卡宾策略,通过钯催化芳基溴化物和腙偶联,合成了芳基-苯乙烯轴手性磷氧化物,该化合物通过转化可以合成轴手性苯乙烯膦配体(Angew.Chem.Int.Ed.2016,55,2186),但该反应只能合成环状的轴手性苯乙烯膦配体,无法合成开环状态的轴手性苯乙烯膦配体,底物适用范围有限。
