Description
技术领域
本发明涉及一种手性三齿氮膦氧配体及其相关配体在不对称氢化反应和类似反应中的应用,属于不对称催化领域。
背景技术
随着人们对光学纯的手性药物、农药、香料和其他精细化学品的需求日益增加,不对称催化技术获得了长足的发展。直接利用氢气对前手性的烯烃、酮和亚胺等不饱和化合物进行催化不对称氢化,由于具有高效、高选择性、高原子经济性的优点,一直是不对称催化领域的研究热点[1]。决定不对称氢化效率的核心因素是金属和配体的有效组合,然而受限于元素周期表,可供选择的过渡金属有限,因此新型手性配体的设计和研发事实上成为不对称氢化领域的最根本的研究主题,贯穿整个不对称氢化历史。
1965年Wilkinson教授报道了第一例均相催化的氢化反应[2]。随后在1968年Knowles教授报道了第一例均相催化的不对称氢化反应[3]。由于具有高效、高选择性、高原子经济性的优点,不对称催化氢化反应在所有已经实现工业化生产的不对称催化反应中占据了70%以上的比重。一些重要的不对称催化氢化反应实现工业化的例子如下:1)Monsanto公司的L-DOPA的合成(脱氢氨基酸的不对称氢化反应,94%ee,运用Rh-DIPAMP催化体系获得2,000转化数)[4],2)Takasago公司L-Menthol的合成是运用Rh-BINAP催化体系取得98%ee和高达300,000转化数[5],3)Norvatis公司的(S)-Metolachlor的合成是运用Ir-ferrocenyl phosphine催化体系催化亚胺的不对称氢化反应,获得80%ee和1,000,000转化数[6-7]。尤其在2012年,BASF公司成功利用不对称氢化反应实现了L-Menthol的10,000吨级合成。
手性配体结构上的微小变化都会对催化不对称氢化反应产生重大影响,这种微妙的构性关系对于配体的设计至关重要,使得化学家可以通过合理的配体位阻和电性设计实现对反应的精细调控。然而并没有一种通用型的配体存在,因此发展高效、高选择性、底物适用范围广的手性配体和不对称催化体系将是永恒的主题。
自Knowles教授的DIPAMP配体和Noyori教授的BINAP配体报道以来,不对称氢化配体的研究主要集中在这两种类型的双齿膦配体的研究上,张绪穆教授在这方面做出了杰出贡献,发展了一系列高效的膦手性和骨架手性的双齿膦配体,建立了一个非常有用的不对称氢化手性配体工具箱[8]。相对于二齿配体,手性三齿配体用于不对称氢化反应的研究则相对较少。理论上,根据Noyori提出的双官能团化机理,双齿膦胺(提供NH)配体即可实现双官能团化机理,周其林教授的手性螺环膦胺配体(SpiroAP)证实了这一点[9]。但与双齿配体相比,三齿配体一般会在过渡金属中心周围提供更深入、更好的“手性口袋”,从而表现出更好的立体选择性。另外三齿配体骨架通常更加稳固不易变形,与金属的结合力更强,使相应的催化剂表现出更高的活性。早在1998年,张绪穆教授就设计合成了一类含双恶唑林环和NH官能团的三齿配体(ph-ambox),并成功应用于芳香酮的高立体选择性不对称转移氢化反应[10]。后来他的课题组又在前面的基础上,设计合成了位阻更加大的indan-ambox,并成功用于简单酮的不对称氢化反应[11]。2011年,周其林教授在手性螺环膦胺配体SpiroAP的基础上增加一个额外的吡啶配位基团得到的SpiroPAP配体对简单酮的不对称氢化反应表现出超高活性[12],但该配体合成复杂,价格昂贵。2013年,张生勇教授在SpiroPAP配体的基础上设计合成了一类二茂铁基的手性三齿配体,该配体在芳香酮的不对称氢化中表现出较高活性,但只能获得中等的ee值[13]。
几种典型的不对称氢化三齿配体如下:
相较于已有的三齿配体,本发明提出了一个合成路线简单,收率高,易于大规模制备,结构和电性质便于调节的新型三齿手性配体,该配体已在催化不对称氢化反应中表现出高活性和高选择性,具有广阔的工业应用前景。

本发明提供催化不对称氢化反应的催化剂,由上述本发明提供的三齿配体与过渡金属前体络合而成。

在本发明中涉及到的全新配体可用于多种不同类型的不对称催化反应,如:不对称氢化反应,不对称转移反应,烯丙基化反应,不对称氢甲酰化反应,硅氢化反应,硼氢化反应,烯烃复分解反应,异构化反应,Diels-Alder反应,不对称偶联反应,Aldol反应,Michael加成反应,不对称环氧化反应,动力学拆分和[m+n]环化反应等。
本发明中配体的磷原子可以以膦氧,膦硫和硼烷保护的形式存在。
以下给出了本发明部分优选的三齿配体实例(L1-L24),每一个配体对应两种对映异构体,也是本专利的内容,具体如下:
本发明还提供了催化剂的制备过程:本发明的三齿配体与过渡金属前体在合适的溶剂中络合反应若干时间。同时还提供了该催化剂催化的酮类化合物的不对称氢化反应案例。
合适的过渡金属有Ru、Rh、Ir、Fe、Co、Ni、Ti、V、Re、Mn。
合适过渡金属前体包括[Rh(NBD)2]+BF4 -;[Rh(NBD)Cl]2;[Rh(COD)Cl]2;[Rh(COD)2]+X-;Rh(acac)(CO)2;Rh(ethylene)2(acac);[Rh(ethylene)2Cl]2;RhCl(PPh3)3;Rh(CO)2Cl2;Ru(aryl group)X2;RuHX(L)2(diphosphine);RuX2(L)2(diphosphine);Ru(arene)X2(diphosphine);Ru(RCOO)2(diphosphine);Ru(methallyl)2(diphosphine);Ru(arylgroup)X2(PPh3)3;Ru(COD)(COT);Ru(COD)(COT)X;RuX2(cymene);Ru(COD)n;RuCl2(=CHR)(PR′3)2;Ru(arylgroup)X2(diphosphine);RuCl2(COD);(Ru(COD)2)X;RuX2(diphosphine);Ru(ArH)Cl2;Ru(COD)(methallyl)2;[Ir(NBD)Cl]2;[Ir(NBD)2]X;(Ir(COD)Cl)2;[Ir(COD)2]X;(Ni(allyl)X)2;Ni(acac)2;Ni(COD)2;NiX2;MoO2(acac)2;Ti(O-iPr)4;VO(acac)2;MeReO3;MnX2;Mn(acac)2;CoCl2;Fe(OAc)2。

本发明提供的三齿配体,相对于ambox类配体,本发明中的配位磷原子具有更强的给电性,而且电性易于调节,这使得金属负氢物种具有更强的亲核性,催化剂活性显著提高。相对于SpiroPAP类配体,本发明中的配体可由廉价易得的Ugi-amine和手性氨基酸经数步反应高收率的获得,并且该配体空气稳定,易于纯化,可通用简单的片段调控配体的位阻和电性,非常适于大规模合成制备,潜在的工业应用价值更大。
配体和金属是催化反应的核心,通过对配体环境的微调即可对反应产生重大影响,因此配体的可调性在很大程度上决定了催化剂的底物适用范围,不同的底物可能需要不同位阻和电性的配体来催化实现高反应性和高选择性。本发明的配体无论在空间位阻还是电性上都非常易于调控,因此可能具有广泛的底物适用范围。
