The benzo-2-pyrone nucleus of the simple coumarins derives from the phenylacrylic skeleton of cinnamic acids. The coumarin structure is derived from cinnamic acid via ortho-hydroxylation (a), trans-cis isomerisation of the side chain double bond (b) and (c), and lactonisation (d). The trans form is stable and could not cyclise, therefore, there should be isomerisation of some sort and the enzyme ...
