技术领域
本发明属于轴手性化合物领域,具体涉及一种EBINOL轴手性化合物及其合成方法和应用。
背景技术
自1980年以来,带有轴手性1,1'-联萘骨架的BINOL作为不对称过渡金属催化的配体而广泛应用。但是对于某些类型的反应,对映选择性效果不佳,因此,又开发了TADDOL和SPINOL手性骨架的配体。目前在寻找不对称反应的配体或者催化剂时,通常同时筛选BINOL和SPINOL衍生物。轴手性BINOL和SPINOL化合物已经广泛应用于不对称催化领域,然而仍然有必要探索新型结构骨架的轴手性配体。
发明内容
炔烃的官能化是构建烯烃的有效方法之一,炔烃的活化通常依赖于过渡金属催化。2012年,Freccero的研究小组用2-亚炔基酚通过辐射的激发态质子转移获得亚乙烯基-醌甲基化物(VQMs),在接下来的几年中,Irie和Yan的研究小组先后报道了利用手性有机碱催化的不对称分子内杂Diels-Alder反应原位形成VQMs。这些结果表明,邻羟基苯基能够在没有过渡金属催化的温和条件下实现炔基官能化,通过VQM可以对炔烃的分子间亲核加成进行轴手性控制。手性双功能酸用于许多不对称反应,发明人设想手性酸能够活化炔烃进而提供亲电子VQM,随后加入亲核萘酚,最终形成EBINOL。
本发明的目的是设计一种双取代的EBINOL(1,1'-(乙烯-1,1-二基)联萘酚)化合物,这种轴手性骨架可以作为BINOL和SPINOL配体/催化剂的有益补充。
本发明的另一目的是提供该EBINOL轴手性化合物的合成方法。

EBINOL手性磷酸的应用
为了证明EBINOL手性磷酸在不对称催化中应用价值,选择了几种先前用BINOL和SPINOL手性磷酸催化的反应。
首先尝试了吲哚和亚胺10a或11a之间的有机催化不对称Mannich反应,在ECPA的催化下,以优异的产率和较好的对映选择性顺利获得产物10b和11b。相比之下,具有相同3,5-双(三氟甲基)苯基的BINOL和SPINOL衍生的手性磷酸结果较差。
通常,需要对具有不同取代基的催化剂进行广泛筛选,才能获得立体选择性较好的BINOL和SPINOL手性磷酸。然而,在没有筛选的情况下,第一个EBINOL衍生的手性磷酸已经显示出很好的立体选择性,这一结果说明EBINOL骨架衍生的手性磷酸具有很好的应用前景。而且基于相似的结构,7b~7v也可以衍生出相应的手性磷酸催化剂。
在氩气保护下,向装有搅拌棒的干燥Schlenk管中加入吲哚(23.4mg,0.20mmol),ECPA(0.85mg,0.001mmol)和PhCl(4.0mL),向溶液中加入10a(16.1mg,0.10mmol)。在室温下搅拌36小时后,将溶液经硅胶柱色谱纯化,用PE/EA洗脱,得到34.3mg 10b,为白色固体(91%收率,70%ee)。
1H NMR(400MHz,CDCl3)δ8.02(s,1H),7.52(d,J=8.2Hz,2H),7.25(t,J=7.7Hz,2H),7.23–7.16(m,5H),7.13(t,J=7.6Hz,1H),7.06(d,J=8.0Hz,2H),6.97(t,J=7.6Hz,1H),6.61(d,J=2.0Hz,1H),5.83(d,J=7.1Hz,1H),5.25–5.21(m,1H),2.34(s,3H)。13C NMR(101MHz,CDCl3)δ143.10,140.37,137.46,136.63,129.33,128.39,127.41,127.30,127.22,125.46,124.00,122.49,119.93,119.31,116.29,111.45,55.15,21.55。M.P.158-160℃。HPLC条件:HPLC DAICEL CHIRALPAK IB,正己烷/异丙醇=80/20,1.0mL/min,λ=214nm,tR(minor)=13.54min,tR(major)=20.4min,ee=70%。
用热风枪加热装有(200mg)的Schlenk管10分钟,活化分子筛。待冷却后,在氩气保护下加入吲哚(23.4mg,0.20mmol),ECPA(4.3mg,0.005)和PhCF3(3.0mL),在-10℃下向溶液中加入11a(16.1mg,0.10mmol),在-10℃下搅拌72小时后,将溶液直接经硅胶柱色谱纯化,用PE/EA洗脱,得到25.5mg 11b,为黄色固体(95%收率,73%ee)。
通过与文献方法获得的S-11b的HPLC数据比较来确定11b的绝对构型。
1H NMR(400MHz,CDCl3)δ8.23(s,1H),7.49(d,J=8.0Hz,1H),7.41(d,J=7.5Hz,1H),7.37–7.31(m,3H),7.27–7.23(m,1H),7.18(t,J=7.6Hz,2H),7.06(t,J=7.5Hz,1H),6.69(d,J=2.5Hz,1H),6.34(s,1H),2.34(s,3H),2.02(s,3H)。13C NMR(101MHz,CDCl3)δ169.52,145.42,137.21,128.34,126.97,126.33,124.86,123.24,122.71,122.31,120.33,119.88,111.84,59.44,26.75,24.58。IR(KBr,cm-1)3433,3203,3183,1661,1489,748。M.P.202-205℃。 (c=0.4,CHCl3)。HPLC条件:HPLC DAICEL CHIRALPAK AD3,正己烷/异丙醇=90/10,1.0mL/min,λ=214nm,tR(minor)=18.66min,tR(major)=21.16min,ee=73%。

EBINOL手性亚磷酰胺的应用
手性亚磷酰胺已经在过渡金属催化的不对称反应中成为通用的配体,EBINOL衍生的手性亚磷酰胺Phos-a在Rh(I)催化的烯酰胺氢化方面非常有效。Phos-a的非对映异构体Phos-b用于Cu(II)催化的加成反应,具有优异的产率和对映选择性。相比之下,SPINOL和BINOL衍生的亚磷酰胺(Phos-bs,br,ss,sr)不能得到满意的结果,这说明EBINOL是1,1'-联萘和1,1'-螺二茚骨架的有益补充。而且基于相似的结构,7b~7v也可以衍生出相应的手性亚磷酰胺催化剂。
在氩气保护下,向装有搅拌棒的干燥Schlenk管中加入Rh(cod)2BF4(根据J.Am.Chem.Soc,137,13748-13751(2015)制备,0.41mg,0.001mmol),Phos-9a(1.37mg,0.002mmol)和脱气的iPrOH(2.0mL),然后在室温下搅拌2小时。随后,在N2保护、手套箱中,将澄清溶液与13a(根据J.Org.Chem,76,339-341(2011)制备)一起转移到装有搅拌棒的4.0mL小瓶中。将小瓶置于钢制高压釜反应器中,将高压釜冷却至-0℃,然后用H2(<30bar)吹扫三次,之后,高压釜加压30bar H2,反应在0℃下搅拌24小时。随后将高压釜缓慢减压,然后浓缩反应溶液,TLC观察表明原料已被完全消耗。通过TLC制备硅胶板纯化残余物,用PE/EA洗脱,得到31.9mg 12b,为白色固体(100%转化率,98%收率,86%ee)。
通过与R-12b的HPLC数据比较确定12b的绝对构型,R-12b是由R-1-苯基乙胺酰化而得。
