Synthesis, anti-virus and anti-tumour activities of dibenzylbutyrolactone lignans and their analogues

An efficient synthesis of dibenzylbutyrolactone lignans and their analogues has been developed. Based on a Stobbe condensation of piperonal or veratraldehyde with diethylsuccinate and alkylation with 3,4- methylenedioxybenzyl bromide to give the skeleton

Isokaerophyllin, a butyrolactone from Bupleurum salicifolium

From the leaves of Bupleurum salicifolium two benzylidene-benzyl-γ-butyrolactone-type lignans were isolated. One was identified as kaerophyllin, the other as its cis-isomer, hitherto unreported. The latter was characterized as 2(3,4-dimethoxy)-benzylidene
