Deskripsi
The title compound, C34H54O5, was synthesized by the reaction of ursolic acid with ethyl chloroacetate in the presence of DMA. All six-membered rings of the pentacyclic triterpene skeleton adopt chair conformations. In the crystal structure, molecules are linked by intermolecular O—H...O hydrogen-bond interactions, forming zigzag chains along the c axis.
