  Lipase‐Catalyzed Esterification of a (±)‐2,3‐Di(Arylmethyl)‐1,4‐butanediol and Its Application to the Synthesis of (S,S)‐(+)‐Hinokinin

  摘要：

  Racemic trans-2,3-di[(3,4-methylenedioxy)benzyl]-1,4-butanediol (dihydrocubebin) 6 was enantioselectively esterified using lipases as catalysts with vinyl acetate. Optically active (SS)-1,4-butanediol 6 obtained was selectively oxygenated with a Fetizon reagent, affording (SS)-(+)-hinokinin 9 in a high yield.

  and seven analogues. Four natural lignans were prepared by this method, and five lignans were synthesised for the first time. The synthesised compounds were evaluated for anti-HIV, anti-HSV, and anti-tumour activities. Results showed that the dibenzylbutyrolactone lignans and their analogues were inactive against HIV Tat transactivation and HSV-1 in vitro, but some compounds displayed significant activity
