A ruthenium-catalyzed photoredox coupling of substituted N-aryltetrahydroisoquinolines (THIQs) and different bench-stable pyridinium salts was successfully developed to give fast access to 1-benzyl-THIQs. Furthermore, secondary alkyl and allyl groups were also successfully introduced via the same method. Additionally, the typically applied N-phenyl group in the THIQ substrate could be replaced by the cleavable p-methoxyphenyl (PMP) group and successful N-deprotection was demonstrated.
一种以钌催化的光氧还偶联反应成功地将取代的N-芳基四氢异喹啉(THIQs)与不同的台阶稳定吡啶盐成功地结合,快速获得1-苄基-THIQs。此外,次烷基和烯丙基基团也成功地通过相同的方法引入。此外,THIQ底物中通常应用的N-苯基基团可以被可裂解的p-甲氧基苯基(PMP)基团取代,并且成功地展示了N-去保护。
