Ethoxy­carbonyl­methyl ursolate

The title compound, C(34)H(54)O(5), 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 hyd...

description The title compound, C(34)H(54)O(5), 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.
