- Title:
- A PROCESS FOR THE PRODUCTION OF (-) 3,4-DIVANILLYL TETRAHYDROFURAN
- Abstract:
- The present invention relates to a process for the production of (-)3,4-divanillyl tetrahydrofuran by isolating (-) secoisolariciresinol from the heartwood and roots of Taxus wallichiana by an improved process which consists of partitioning of the alcoholic extract for the heartwood and roots of T. wallichiana between water and chlorinated solvent, extracting the chlorinated solvent extract with alkali and isolating (-) secoisolariciresinol from the alkali extract upon neutralization with mineral acid and extracting with organic solvent crystallizing it from suitable organic solvent, dissolving the isolated (-) secoisolariciresinol in suitable organic solvent and reacting with triphenyl phosphine halide at 0-80°C for 1-10 hours and isolating (-)3,4-divanillyl tetrahydrofuran by column chromatography.
