Keyword(s):
The structure of the eleventh in the series of novel lignans from the heartwood of western red cedar (Thuja plicata Donn) has been determined as 1,4-dihydronaphthalene-6-hydroxyl-2-(hydroxymethyl)-7-methoxy-4(3′,4′-dihydroxy-5′-methoxyphenyl)-3-carboxylic acid lactone (β-apoplicatitoxin) (1) by spectrometric methods and by aromatization to the known compound trimethylplicatinaphthalene. This lignan provides an intermediate to the possible stereoselective synthesis of derivatives related to the picropodophyllin series.
