Description
技术领域
本发明属于有机氘代化合物合成领域,具体涉及一种钯催化C-1氘代芳香醛的合成方法。
背景技术
氘代技术对药学、材料科学、生物化学以及实验测试等领域都有很大的影响。2017年,梯瓦TEVA公司研发的Austedo成为美国食品与药品监督管理局获批的首个氘代药物。因此有关氘代化合物的合成深受有机化学工作者的关注。芳香醛是一类重要的有机化合物,不仅是众多具有生物活性分子的重要片段,还是合成材料、药物和农用化学品的重要中间体。
近些年,各国有机化学工作者投入到有关C-1氘代芳香醛的合成当中。生成C-1氘代芳香醛的经典方法主要依赖于羧酸酯或酰胺与氘代还原试剂的还原-(氧化)反应(Angew.Chem.Int.Ed.2015,54,15525,J.Am.Chem.Soc.2007,129,3408-3419);光催化苯甲酸脱羟氘化反应(Angew.Chem.Int.Ed.2019,58,312-316);钯/铑共催化芳基卤化物醛基化反应(Angew.Chem.Int.Ed.2018,57,10362-10367)以及自由基介导的醛类化合物氢/氘交换反应策略(Angew.Chem.Int.Ed.2017,56,7808-7812,Nature Catal.2019,2,1071-1077,ACS Catal.2021,11,14561-14569,Chem 2019,5,2484-2494,ACS Catal.2020,10,2226-2230,Chem.Sci.2020,11,1026-1031,Chem.Sci.2020,11,8912-8918)。然而,这些方法往往受限于苛刻的反应条件进而影响到底物适用范围,而且有些条件下产物氘代氯较低,且氘代选择性较差。很难应用于工业生产实际应用当中。所以开发一种原料易得、底物适用范围广,高效率、高选择性、高氘代率的合成C-1氘代芳香醛,在氘代化学品以及氘代药物的合成当中具有重要的实用意义。
