## Abstract The ^13^C spectra of eleven 9,10‐dihydrophenanthrene and twelve phenanthrene derivatives were recorded in order to examine the effects of hydroxy and methoxy substitution on the skeletal carbon shieldings. For each series, the parent compounds were the 2,4‐disubstituted derivatives with

✦ Synopsis
To date, about twenty 9, IO-dihydrophenanthrene derivatives have been isolated from nature. Although 9, IO-dihydrophenanthrenes have been known ' for over a decade, most of the members of this group of compounds have been isolated 2-5 in recent years. Many of these compounds are phytoalexins6 and one of them,iuncusol (l),is highly cytotoxic.
