SYNTHESIS OF FLUOROPHORES BASED ON BENZO[<i>g</i>]COUMARIN FRAMEWORK

Аннотация

This microreview summarizes and analyzes literature for the years 2016–2023 on the construction of fluorophores based on benzo[g]coumarin backbone, which represent a push–pull system consisting of an annulated benzo and pyran rings. The main approaches to the synthesis of benzo[g]coumarins are condensation reactions, cyclization reactions, and pyran ring opening reactions followed by recyclization.
