Description
技术领域
本发明涉及作为光催化剂有用的新颖吖啶鎓盐及其制造方法。
背景技术
已知7-羟基-3,4,12,12a-四氢-1H-[1,4]噁嗪酮[3,4-c]吡啶酮[2,1-f][1,2,4]三嗪-6,8-二酮等3环吡啶酮衍生物作为具有帽依赖性核酸内切酶抑制活性的取代多环吡啶酮衍生物的母核骨架,此外,也已知其与作为具有HIV整合酶抑制活性的化合物等其它药物而有用的化合物共通的骨架。正在开发用于合成这些作为药物有用的化合物的共通的骨架部分的更适合工业生产的方法。
专利文献1-14描述了如下所述的使用(R)-氨基醇生产度鲁特韦(dolutegravir)的立体选择性方法。
(式中,RA1为羟基,烷氧基或卤素等;RA2为氢,二氟苄基氨基甲酰基,烷氧基羰基或羧基等;RA3为醛或醛等价物;RA4为烷基等。)
专利文献15~16中记载了合成7-(苄氧基)-3,4,12,12a-四氢-1H-[1,4]噁嗪酮[3,4-c]吡啶酮[2,1-f][1,2,4]三嗪-6,8-二酮的以下对映体混合物,然后进行光学分离以合成光学活性物的下述制造方法。然而,这种合成方法并不高效,原因在于其是在合成了对映体混合物(1:1)之后再得到具有所需立体构型的化合物。
专利文献17描述了一种立体选择性环化的方法,如下所示,通过在与酰胺相邻的碳上设置一个光学活性的酯基,在立体选择性环化之后,然后将酯基水解为羧基,再在吖啶鎓盐的存在下通过光照射使羧基脱离。该脱离反应的反应时间长达14小时,作为商业化生产方法来说存在问题。
