Description
技术领域
本发明属于有机合成制备技术领域,涉及化合物的不对称催化,具体涉及一种手性吡啶醇衍生物的制备方法。
背景技术
手性吡啶醇结构广泛地存在于天然产物和新型功能材料等物质当中,也是多种药物的重要骨架,比如含有手性吡啶芳基醇结构的卡巴沙明和苯磺酸贝他斯汀是两种常用的组胺受体拮抗剂;由手性吡啶烷基醇结构为骨架的化合物A是一种在研的抗癌药物;除此之外,多种手性吡啶烷基醇是部分工业应用催化剂配体的中间体成分。
如何简单、廉价、高效地获取手性吡啶二级醇是亟需解决的问题。目前,手性吡啶醇衍生物的不对称合成方法可分为三大类:(1)芳基有机金属试剂与杂芳香醛的不对称加成;(2)生物催化技术;(3)不对称催化氢化。其中,通过均相不对称催化得到的手性吡啶醇产物构型单一,反应过程产生的化学废料少,基本没有副产物的产生,因而从实际应用和原子经济性角度考虑,不对称催化氢化方法是最有吸引力的。
2000年,Noyori小组(Pure Appl.Chem.,2001,73(2):227-232)以在简单非官能化酮的不对称催化上展现出优异还原能力的Ru双膦双胺催化剂——Ru(II)X2-BINAP-diamine为催化剂,对2,3,4-吡啶烷基酮和吡啶二酮的不对称氢化进行了研究。研究发现该体系在以B[OCH(CH3)3]为添加剂的条件下,可实现对吡啶酮类底物的高效还原(S/C=2000,产物ee值大于94%),反应效果最好的吡啶二酮可在S/C为10000的情况下,得到100%转化,ee值大于99.9%的手性吡啶二醇。
2003年和2008年,Cheng-yi Chen(Organic Letters,2003,5(26):5039-5042)和Francine(Tetrahedron,2008,64(37):8700-8708)小组研究了Ru(II)X2-BINAP-diamine催化体系对吡啶芳基酮的不对称催化。实验结果显示该体系在适当条件下可实现可对在芳环邻位有取代基的吡啶芳基酮的高效不对称氢化还原,产物的ee值达到99%(S/C=1000)。但当苯环上没有取代基或取代基在其他位置时,体系的选择能力大幅下降。
2012年,张兆国课题组(The Journal of Organic Chemistry,2012,77(1):612-616.)将Noyori双膦双胺催化剂的双膦配体更换为新发展的SunPhos配体,对吡啶酮类底物的不对称氢化进行了研究。该体系在对此类底物的催化还原上展现出比Noyori双膦双胺催化剂更强的催化能力,但和之前的实验结果类似,体系对底物的高选择性依赖于底物上存在芳环邻位取代基。
尽管过渡金属催化不对称氢化制备吡啶醇衍生物有了长足的进展,但仍有几个重要问题尚未解决:(1)转化数(TON)太低,TON≤2000,无法满足工业生产的要求;(2)催化体系单一,仅限于双膦配体和钌或铑金属盐;(3)底物普适性较差,吡啶环上的取代基位置对ee值影响较大。这些都是吡啶醇衍生物的工业化合成急需解决的问题。因此,寻找一种高效、高立体选择性、底物适用性广的不对称催化氢化新方法具有重要的现实意义。
