                                A competent and general asymmetric synthesis of 7'-hydroxydibenzylbutyrolactone lignans such as (7'S)-hydroxymatairesinol and (7'S)-hydroxyarctigenin has been reported from N-succinyl-2-oxazolidinone in six steps where diastereoselective aldol reaction and stereoselective alkylation serve as the key steps.
