Yoshikawa, Chisato published the artcileConstruction of 7-diethylaminocoumarins promoted by an electron-withdrawing group, Recommanded Product: 2-Phenylethanethiol, the publication is Chemical & Pharmaceutical Bulletin (2021), 69(7), 608-611, database is CAplus.
The coumarin skeleton has been a focus of attention for many years, and its fluorescence properties vary depending on the substituents. Fluorescent coumarin derivatives I (R = OMe, diethylaminyl; R1 = (2-phenylethyl)sulfanyl, phenyloxidanyl, (2-phenylethyl)oxidanyl, etc.) are useful tools for many strategies and have been developed for their synthesis. Although 7-diethylaminocoumarins I has excellent fluorescence properties, it is unstable. A facile strategy for the synthesis of 7-diethylaminocoumarin derivatives I by increasing the electrophilicity of the ynone moiety to promote nucleophilic addition reactions and cyclization have been developed. The reaction tolerates a variety of substitutions at the 4-position.
