Abstract

The coumarin subunit is found in many natural products displaying diverse biological activities. 1 They are widely used as additives in food, perfumes, agrochemicals, cosmetics and pharmaceuticals, and in the preparation of insecticides. 2 The synthetic coumarin dyes exhibit strong fluorescence and are used as active lasing media, fluorescent probes for investigation of biological objects, and optical bleachers. 3 Their diverse properties make coumarins ...
