A convenient and rapid approach for the syntheses of (-)-kaerophyllin (1),(-)-hinokinin (2) and (±)-isohinokinin (3) was described. The key steps were involved in condensation of aromatic aldehyde and alkylation of the resulting ester to give the complete skeleton of dibenzylbutyrolactone-lignan. Hydrolysis,followed by resolution with quinine,reduction and when appropriate,oxidation gave the title compound. The asymmetric total synthesis of the kaerophyllin (1) was reported for the first time.
