چکیده

The title compound, C(20)H(28)O(2), commonly named Sugiol, is a natural oxygenated diterpene that we have isolated for the first time from a hexane extract of the fruits of Juniperus Oxycedrus L. Its X-ray crystal structure determination confirms an abietane skeleton which was predicted by spectroscopic analysis, mainly by (1)H and (13)C NMR. The cyclo-hexane ring adopts a flattened chair conformation, while the cyclo-hexene ring adopts an envelope conformation. The mol-ecules are linked through O-H⋯O hydrogen bonds to form a zigzag chain extending parallel to the c axis.

The new title diterpenoid compound, C(20)H(30)O, is a natural product isolated from Tetra-clinis articulata wood via chloro-form extraction. The asymmetric unit contains four mol-ecules with the same S,S configuration, deduced from the chemical synthesis. Indeed, an overlay analysis, calculated using structure-matching software, shows that the four mol-ecules can be superimposed. The central ri...

The title compound, C(20)H(26)O(2), was isolated from a chloro-form extract of Tetra-clinis articulata wood. The mol-ecule contains three fused rings which exhibit different conformations. The non-aromatic oxo-substituted ring has a screw-boat conformation, while the central ring has a half-chair conformation. In the crystal, mol-ecules are linked to each other by inter-molecular O-H⋯O hydrogen...

In the title compound, C(21)H(26)F(3)NO(6) (+)·CF(3)COO(-)·CH(3)OH or S-MNTX·CF(3)COO(-)·CH(3)OH (MNTX = methyl-naltrexone), the conformation of the polycyclic backbone of the noroxy-morphone skeleton can be simplified in terms of the angles between the least-squares planes of these rings. The dihedral angle between the cyclohexene and piperidine rings is 84.5 (6)°, while the dihedral angles be...
