The R,7aS,8R,10S,12R,13aR,13bS)-methyl 10-hydroxy-5,5,7a,10,12,13b-hexamethyl-14-methylene-3,9,11-trioxohexadecahydro-8,12-methanocycloocta[3,4]benzo[1,2-c]oxepine-8-carboxylate], C26H36O7, has been determined by using Cu Kα radiation [Flack parameter = 0.07 (15)]. The structure is consistent with that reported previously [Stierle et al. (2011). J. Nat. Prod. 74, 2272–2277], determined by detailed analysis of MS and NMR data. The molecule consists of a fused four-ring arrangement. The seven-membered oxepan-2-one ring has a chair conformation, as do the central cyclohexane rings, while the outer cyclohexa-1,3-dione ring has a boat conformation. In the crystal, molecules are linked via O—H⋯O hydrogen bonds, forming helical chains propagating along [100].

Berkeleydione, preaustinoid A and the title compound, preaustinoid A1, were co-isolated from the organic extract of Penicillium rubrum (Stierle et al. 2011). Colorless crystals of the title compound were grown by vapor diffusion of pentane into a chloroform solution.
All the H atoms were located in difference Fourier maps and the hydroxyl H atom was freely refined. The C-bound H atoms were finally placed in calculated positions and refined using a riding model: C—H = 0.95 - 1.0 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for other H atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
