520 3 |a (±)-1-oxoferruginol and (±)-shonanol, two potential intermediates in the synthesis of tricyclic diterpenoid ferruginol, have been prepared and crystal structures of the compounds have been investigated using single-crystal X-ray diffraction data. The methyl groups of the isopropyl moiety in (±)-shonanol are disordered over two positions with occupation factors 0.65(1) and 0.35(1), respectively. Although the chemical structures of two compounds are very similar, a C—C single bond in the terminal six-membered ring of (±)-1-oxoferruginol is replaced by a C=C bond in (±)-shonanol, the quantitative isostructurality index calculations indicate that the structures are not isostructural. Intermolecular O—H O hydrogen bonds between pairs of molecules in the compounds related by center of inversion lead to characteristic dimers forming R22(16) rings. The molecular conformation of (±)-1-oxoferruginol obtained from the semi-empirical quantum mechanical AM1 calculation shows good agreement with the X-ray structures.
