Over the past 150 years, since Vogel in 1820 isolated the parent oxygen heterocycle, coumarin (1) from Coumarouna odorata = Dipteryx odorata (1), coumarins have been recognized as widely distributed plant products. The vast majority carry an oxygen substituent at C-7; consequently 7-hydroxycoumarin [umbelliferone, (2)], one of the most widely distributed coumarins, is often regarded as the parent, in a structural sense and also biogenetically, of a large number of the structurally more complex…

Medicinal Potential and Biosynthesis of Plant Coumarins
TLDR
Coumarins comprise a large group of natural compounds isolated from many plant or microbial sources, and novel derivatives are still being reported each year, but the mechanism of coumarin biosynthesis has been resolved only partially and significant progress has been accomplished recently.
Progress in the Chemistry of Naturally Occurring Coumarins.

TLDR
Coumarin chemistry remains one of the major interest areas of phytochemists, especially because of their structural diversity and medicinal properties, along with the wide-ranging bioactivities of these compounds, inclusive of analgesic, anticoagulant anti-HIV, anti-inflammatory, antimicrobial, antineoplastic, antioxidant, and immunomodulatory effects.
Coumarin: A Natural, Privileged and Versatile Scaffold for Bioactive Compounds
TLDR
An overview of the most recent synthetic pathways leading to mono- and polyfunctionalized coumarins will be presented, along with the main biological pathways of their biosynthesis and metabolic transformations.

Polyketide derivatives active against Botrytis cinerea in Gerbera hybrida
TLDR
It is shown that gerbera plants transformed with the gene for 2PS in an antisense orientation and unable to synthesise gerberin and parasorboside are susceptible to Botrytis cinerea infection.

TLDR
These Pelargoniums have thus represented an attractive source of fascinating secondary metabolites and a notable wealth of highly oxygenated simple coumarins and a number of miscellaneous uncommon metabolites.
Functional characterization of a Mg(2+)-dependent O-methyltransferase with coumarin as preferred substrate from the liverwort Plagiochasma appendiculatum.
TLDR
The catalytic capacities of the studied protein suggest that two routes to scopoletin might co-exist in liverworts in that the enzyme involved in the methylation process participates in both paths, but especially the route from esculetin.
