Ethoxy-carbonyl-methyl ursolate.

ABSTRACT: The title compound, C(34)H(54)O(5), was synthesized by the reaction of ursolic acid with ethyl chloro-acetate in the presence of DMA. All six-membered rings of the penta-cyclic triterpene skeleton adopt chair conformations. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O hydrogen-bond inter-actions, forming zigzag chains along the c axis.
