Electroreduction of Coumarin. The principal cathodic reaction of coumarin is the reduction to melilotic acid (Fig. 10.18). A second reduction product is an approximately equimolar mixture of o-hydroxyphenylpropanol and o-propylphenol (Fig. 10.18). Hence, there are three reactions involving coumarin.

Melilotic acid (2-hydroxyhydrocinnamic acid, hydro-coumaric acid). 

Infrared spectroscopy was one of the tools used (Levy and Frost, 1966) for a definitive identification of 2,3-dihydroxyphenylpropionic add, the product from the reaction between the enzyme, melilotate hydroxylase (from extracts of the Arthrobac-ter species), and melilotic acid, NADH, and oxygen. 

Dicoumarol is formed from melilotic acid (Fig. 299) by some microorganisms, e.g., Aspergillus fumigatus. The carbon of the methylene bridge may originate from a formaldehyde-equivalent. Dicoumarol is the toxic factor of decaying sweet clover (Melilotus officinalis). It inhibits blood coagulation.
