Description
技术领域
本发明涉及一种手性3,3-二取代异吲哚啉酮类化合物的合成方法。
背景技术
3,3-二取代手性异吲哚啉酮类骨架在医药、生物以及合成化学等领域得到广泛的应用,探索合成吲哚骨架的有效方法已经成为一个很重要的研究领域。3,3-二取代手性异吲哚啉酮类化合物因其独特的生物和药物活性,受到了有机合成工作者的广泛关注。在现有的文献中主要是通过异吲哚啉酮3-位对映选择性官能化实现双取代手性异吲哚啉酮骨架的构建,但是这种策略不可避免的导致底物合成困难,原子和步骤经济性低、产物的多样性和复杂性难以满足等缺点。发展新的合成方法,从简单易得的底物出发,高效高选择性实现手性异吲哚啉酮类化合物的构建值得期待。
过渡金属催化的C-H键直接官能化反应无需底物的预活化过程实现目标产物的构建,近年来成为有机合成的热点和难点领域。炔烃作为常见的偶联组分通常作为二碳合成子参与环化,合成重要的五元或六元化合物。但是炔烃作为一碳合成子实现的转化非常罕见。2014年Lam课题组首次以烯炔类化合物为一碳合成子实现了[5+1]环化反应构建了含季碳中心的内酯类化合物(Angew.Chem.Int.Ed.,2014,53,9931)。2019年我们课题组以N-甲氧基苯甲酰胺为芳烃底物,铑催化下实现了与烯炔类化合物的[4+1]环化反应构建了异吲哚酮衍生物(Org.Lett.2019,21,1789)。但是烯炔参与的对映选择性[4+1]环化反应尚未实现。我们通过商业易得的手性茂基配体制备手性铑催化剂(Angew.Chem.Int.Ed.2019,58,8902;Angew.Chem.Int.Ed.2020,59,2890.),将C-H键活化和对映选择性烯丙基取代反应相结合,从简单易得的N-甲氧基苯甲酰胺和烯炔类底物出发,通过对映选择性[4+1]环化反应实现了3,3-二取代手性异吲哚啉酮类骨架的一步构建。
