Abstract

The title compound, C(21)H(21)BrO(7)·C(2)H(6)O, was synthesized by the Claisen-Schimidt reaction of helicid (systematic name: 4-formyl-phenyl-β-d-allopyran-oside) with 4-bromo-aceto-phenone in ethanol. The pyran ring adopts a chair conformation. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular O-H⋯O hydrogen bonds.

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.
