Metabolic activity of DMAPP and IPP sometimes results in prenylation of plant phenolics leading to prenyl ethers, several of which hare been isolated from woody tissues. For example, imperatorin (12), a prenylated coumarin, is present in the roots of Imperatoria ostruthium (228). From African sneezewood Ptaerox-ylon obliquum, prenyletin (13) was obtained along with several other coumarins (125). Another example of a naturally occurring prenyl ether is the isoflavone, maxima-substance C (14) from roots of Tephrosia maxima (229). Several other ex-...
