Described here is the denovo design and synthesis of a series of 6H-dipyrido[1,2-e:2′,1′-i]purin-6-ones (DPs) as a new class of visible-light photoredox catalysts (PCs). The synthesized DP1–5 showed their λAbs(max) values in 433–477 nm, excited state redox potentials in 1.15–0.69 eV and −1.41 to −1.77 eV (vs. SCE), respectively. As a representative, DP4 enables the productive guanylation of various
本文描述了一系列 6 H-联吡啶并[1,2- e :2',1'- i ]purin-6-ones (DPs) 作为新型可见光光氧化还原催化剂的从头设计和合成(件)。合成的DP1-5的λ Abs(max)值分别在 433-477 nm,激发态氧化还原电位分别在 1.15-0.69 eV 和 -1.41 到 -1.77 eV(相对于SCE)。作为代表,DP4能够对各种胺进行有效的鸟苷化,包括 1°、2° 和 3°-烷基伯胺、仲胺、芳基和杂芳基胺、氨基腈、氨基酸和肽以及丙炔胺和 α-氨基酯,从而产生多样性在生物学上重要的胍和环状胍中。DP4在鸟苷酸化反应中的光催化功效超过了常用的 Ir 和 Ru 多吡啶基配合物,以及一些有机 PC。该方法的其他显着优点包括广泛的底物范围和官能团耐受性、克级合成和通用的后期衍生化,导致衍生物81对具有 IC 50的拉莫斯细胞表现出 60 倍更好的抗癌活性 比临床药物依鲁替尼
