Description
技术领域
本发明涉及NCP配体、其金属铱络合物、制备方法及应用。
背景技术
1,1-取代芳基烷烃是许多生物活性分子的重要骨架,包括像托特罗定和舍曲林这样的药物分子。而1,1-二芳基乙烷类化合物因其具有潜在的治疗炎症、失眠、癌症、肥胖的功效而受到了科学家们的广泛研究。转金属催化1,1-二芳基乙烯的不对称氢化是构建1,1-二芳基乙烷类化合物最直接有效的方法。尽管转金属催化1,1-二芳基乙烯的不对称氢化已经取得了重大进展,对于邻位含有位阻导向的1,1-二芳基乙烯的不对称氢化反应报道较少。
Diegiez小组报道了手性金属铱催化该类底物的不对称氢化反应(Mazuela,J.;Verendel,J.J.;Coll,M.;Schaffner,B.;Borner,A.;Andersson,P.G.;Pamies,O.;Dieguez,M.J.Am.Chem.Soc.2009,131,12344-12353;Mazuela,J.;Pàmies,O.;Diéguez,M..Eur.J.Inorg.Chem.2013,2139-2145),但是仅有少数的例子被报道,随后Lu课题组报道了廉价金属钴催化的邻位含有氯原子的1,1-二芳基乙烯的不对称氢化反应(Chen,J.;Chen,C.;Ji,C.;Lu,Z.Org.Lett.2016,18,1594-1597.),邻位的氯原子是控制对映选择性的关键。不对称转移氢化反应因其不使用危险的氢气、不使用昂贵的氢化装置、操作简单等优点而受到广泛研究(Gladiali,S.;Alberico,E.Chem.Soc.Rev.2006,35,226-236;C.Zheng;S.-L.You.Chem.Soc.Rev.2012,41,2498-2518;Wang,D.;Astruc,D.Chem.Rev.2015,115,6621-6686.),但转金属催化1,1-二芳基乙烯的不对称转移氢化至今缺少任何报道。
因此,发展一种高效、环境友好的转金属催化体系催化1,1-二芳基乙烯的不对称转移氢化来构建具有生物活性的手性1,1-二芳基乙烷类化合物具有潜在的应用价值。
