- Abstract
Synthesis and structural characterization of new esters of oleanolic acid and its 11‐oxo derivatives are reported. Compounds crystallize in four isostructural groups, each containing one to four structures. Single‐crystal X‐ray analysis revealed that molecules belonging to non‐isostructural groups self‐associate according to two schemes that describe also supramolecular architectures in crystals of glycyrrhetinic acid derivatives. Structural motifs arise as a result of van der Waals forces. Parameters introduced for the analysis of one‐ and two‐dimensional assemblies allow the comparison of motifs in isostructural and non‐isostructural crystals, including polymorphs, and a qualitative assessment of differences in molecular self‐assembly. One‐, two‐ or three‐dimensional similarity has been confirmed by XPac calculations.
