Oligostilbenoids from Dipterocarpaceaeous Plants: A New Resveratrol Tetramer from Vateria indica and the Revised Structure of Isohopeaphenol

摘要

The investigation of phenolic constituents in Vateria indica afforded five resveratrol tetramers, vateriaphenols B and C isohopeaphenol, hopeaphenol, and shoreaketone. Their structures and configurations were established by spectroscopic methods. The structure assigned to vateriaphenol C was found to be identical with the structure reported in the literature for the resveratrol tetramer isohopeaphenol. The structure of isohopeaphenol was revised and confirmed by spectroscopic evidences,
