Description

平面手性茂金属化合物、其合成方法及应用
技术领域
本发明涉及一种平面手性茂金属化合物、其合成方法及应用。该方法可以以取代的茂金属,卤代芳环或卤代杂环芳烃为原料,手性膦配体和铑为催化剂,利用动力学拆分的策略,高效率、高选择性(高对映选择性,高区域选择性)地合成这类平面手性茂金属化合物。这类平面手性茂金属化合物能方便转化为一系列手性配体。
背景技术
平面手性化合物在药物化学,不对称催化和材料化学领域中是非常常见的骨架(Acc.Chem.Res.2000,33,412;Acc.Chem.Res.2004,37,542;Angew.Chem.Int.Ed.2006,45,7674.)。化学家们一直以来致力于发展一类高效的方法将引入平面手性。到目前为止,常用的策略是利用手性辅基或者当量的手性碱。利用上述方法可以合成多种平面手性茂金属化合物,但这些方法具有明显的局限性,如需要预装手性辅基或使用空气敏感的金属试剂。利用不对称催化的方法,尤其是不对称催化碳氢键活化的方法,可以高效快捷地合成平面手性茂金属化合物。
1,2-二取代、1,2,3-三取代和1,3-二取代二茂铁的一般合成反应方案如下(Organometallics 2007,26,3850):
Scheme 1.General Reaction Schemes for the Synthesis of
1,2-Di-,1,2,3-Tri-,and 1,3-Disubstituted Ferrocenes route 1
route 2
上述方法仅能适用于特定基团,取代位置受限,普适性差。
另外需要强调的是,1,3-二取代平面手性茂金属化合物的合成非常具有挑战性,一般在手性导向基的作用下,使用当量碱在邻位引入溴原子,然后再次使用当量碱和亲电试剂反应,在溴的邻位引入所需官能图,最后脱除溴原子,实现手性1,3-二取代平面手性二茂铁化合物的合成(Chem.Commun.2005,4929。Organometallics 2007,26,3850)。
另外,在中国发明专利CN2019108903644中公开的内容,使用的原料II是不涉及手性的底物,其产物的手性完全由手性配体决定,其可高手性纯度的得到目标化合物,所以不存在手性拆分过程,
发明内容
本发明所要解决的技术问题是提供了一种与现有技术完全不同的手性茂金属衍生物及其制备方法和应用。本发明提供了一种新型平面手性茂金属化合物,利用易得的手性膦配体,利用动力学拆分的策略,发展了吡啶导向的不对称偶联反应,高效地合成了平面手性茂金属化合物并可回收光学纯的手性茂金属原料,并且该平面手性茂金属原料可以用于进一步制备手性配体,该手性配体在不对称催化中有着广泛的应用。
