As the anticancer effects of Tropoloisoquinoline alkaloids have proven, the synthesis of their cytotoxic derivatives has been gained great interest in total synthesis. In parallel, also in pharmaceutical chemistry, research on fluorine substitutes, which are biologically active derivatives of original compounds, draws attention. Due to its large electronegativity and small size as similar to a hydrogen atom, it has a unique characteristic of forming a strong carbon-fluoride bond. For this reason, the aim of this study is finding efficient route to synthesize fluorine derivatives of tropoloisoquinoline. With their fluorine derivatives, Structure-activity relationship (SAR) of tropone families also can be conducted. The key step of this research is to synthesize a tropone ring by using the Kende coupling reaction. Phenol precursor, which is key intermediate for Kende’s protocol, was obtained through Suzuki coupling reaction and Reissert-type addition of nitro methyl group to isoquinoline. The isoquinoline skeleton was synthesized by using the PomerantzFritsch reaction stated from commercially available benzyl alcohol.
