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

Isolation, structure and synthesis of new diarylbutane lignans from Phyllanthus niruri: Synthesis of 5'-desmethoxy niranthin and an antitumour extractive

The structures of three new lignans (1-3) and a phenolic lignan (4) isolated from Phyllanthus niruri have been determined. The structures (1-3) were confirmed by their total synthesis and that of (4) was by its conversion to (3). The synthesis of (±) 5'-d
