Light-emitting firefly luciferin analogues contain electron-donating groups in the 6′-position, but the scope of known 6′-substitution remains narrow. A two-step route to a broad range of 6′-substituted luciferin analogues was developed to fill this void and enable more extensive study of the 6′-functionality. This chemistry allowed direct access to “caged” amide and bright azetidine analogues, but also
发光萤火虫萤光素类似物在 6'-位含有供电子基团,但已知 6'-取代的范围仍然很窄。开发了一种获得广泛 6'-取代的荧光素类似物的两步路线,以填补这一空白,并能够对 6'-功能进行更广泛的研究。这种化学反应可以直接获得“笼状”酰胺和明亮的氮杂环丁烷类似物,但也揭示了硫醚抑制剂和出人意料的发光芳胺衍生物。
