Abstract: In the molecule of pinnatane A, C₃₀H₄₈O₃, isolated from the bark of Walsura pinnata Hassk, the four cyclohexane rings adopt chair conformations; the carboxyl and hydroxy substituents occupy axial positions. The cyclohexene ring is envelope-shaped. Adjacent molecules are linked by O-HO hydrogen bonds into a chain running along the c axis.
