Lignans of western red cedar (Thuja plicata Donn). VII. Dihydroxythujaplicatin
Keyword(s):
The structure of a seventh lignan from the hot-water extractive of western red cedar, which was partially separated in a previous paper, has been determined as 2,3-dihydroxy-2-(3″,4″-dihydroxy-5″-methoxybenzyl)-3-(4′-hydroxy-3′-methoxybenzyl)-butyrolactone (I). This lignan is the fifth member of the thujaplicatin series and is trivially named dihydroxythujaplicatin. Methylation, ethylation, and degradation studies provide proof of structure by comparison with known compounds.
