In the title compound, C(23)H(15)BrO(3), the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) Å] and makes a dihedral angle of 5.74 (8)° with the mean plane of the bromo-substituted benzene ring. An intra-molecular C-H⋯O hydrogen bond generates an S(9) ring motif. In the crystal, mol-ecules are linked by C-H⋯O inter-actions,(More)
In the title compound, C(25)H(32)O(3), the enone group adopts an s-cis conformation. The alk-oxy chain is in an all-trans conformation. The dihedral angle between the benzene rings is 7.86 (5)°. In the crystal, mol-ecules are connected by pairs of O-H⋯O hydrogen bonds, forming inversion dimers and giving R(2) (2)(10) rings. Within these dimers, weak C-H⋯O(More)
In the title compound, C(20)H(28)O(4), a diterpenoid isolated from the roots of Premna obtusifolia (Verbenaceae), the five-membered ring is in a half-chair conformation. One six-membered ring exists in a twisted-boat conformation while the other is in half-boat conformation. The crystal packing is stabilized by inter-molecular O-H⋯O and weak C-H⋯O(More)
