Application of a general synthetic pathway for aryltetralin and dibenzylbutyrolactonelignans, starting from the lithium enolate of 3-(3,4-dimethoxybenzyl)butyrolactone (1) led to syntheses of (±)-lintetralin (4), (±)-phyltetralin (5), (±)-isogalcatin (12), and (±)-kusunokinin (13).

The acid-catalyzed rearrangement of diaryl-dilactones, readily obtained by oxidation of ferulic acid derivatives, is examined as a synthesis route to aryltetralins. Two structures which have been proposed for the lignan, phyltetralin, are shown by synthesis of the two diastereomeric 1-veratryltetralins (3A) and (3B), to be untenable. Conidendrin has been converted to isolariciresinol tetramethyl ether
