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
