Abstract: Coumarins (2H-chromen-2-ones) are heterocyclic compounds of wide scientific
interest due to their important biological and pharmaceutical properties such as antitumor,
antioxidant, anti-inflammatory and antimicrobial activities as well as enzymatic inhibitors
related to neurodegenerative diseases. Due to their structural variability, this compound
class has been attracting considerable interest in the natural products and synthetic organic
chemistry areas. Coumarins and their derivatives have been prepared by a variety of methods,
including Perkin, Wittig and Reformatsky reactions, Pechmann and Knoevenagel
condensations, and Claisen rearrangement, among others. In the present review we report
the different synthetic methods used in the preparation of coumarin derivatives exploited
in the last ten years (from 2008 to 2018), regarding the research demand for new structural
scaffolds.
