THE SYNTHESES OF (R)-(+)-β-VANILLYL-γ-BUTYROLACTONE AND OF CHIRAL LIGNANS THEREFROM
Brown, Eric,Daugan, Alain
, p. 1169 - 1172 (2007/10/02)
(R)-(+)-β-vanillyl-γ-butyrolactone was obtained in 4 steps including a resolution, from vanillin and dimethyl succinate, and was used for the total syntheses of 5 naturally occurring and optically active lignans such as (+)-isolariciresinol 20.
