organic compounds
Although the title compound, C43H58O17.0.355C4H8O2, from Entandrophragma cylindricum, exhibits significant disorder in its ester side chains, it was possible to determine the absolute configurations of the (2S)-2-methylbutanoate and (2S)-2-hydroxy-2-methylbutanoate sidechain groups by comparison with the stereochemistry of the core secotetranortriterpenoid skeleton.
