  Asymmetric aldol approach to dibenzylbutyrolactone lignans: synthesis of (−)-(7′S)-hydroxymatairesinol and (−)-(7′S)-hydroxyarctigenin

  摘要：

  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.
