چکیده

The absolute configuration of the title compound, C(18)H(24)O(5)·H(2)O, was not been determined by anomalous-dispersion effects, but has been assigned by reference to an unchanging chiral centre in the synthetic procedure. Intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, O-H⋯O hydrogen bonds link the main mol-ecules and the water mol-ecules, forming an infinite three-dimensional network.

The title compound, also known as cis-zearalenone (cis-ZEN), C(18)H(22)O(5), has already been reported elsewhere [Griffin et al. (1981 ▶). ACA Ser.29, 35], but no atomic coordinates are publicly available. The mol-ecule is of inter-est with respect to its toxicity. In the crystal, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular conformation, while inter-molecular O-H⋯O hydrogen bo...

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...

In the title mol-ecule, C(39)H(45)NO(6), the two tetra-methyl-octa-hydroxanthen-1,8-dione substituents are arranged approximately parallel to each other and approximately perpendicular to the plane of the pyridine ring. The six-membered xanthene rings adopt flattened boat conformations with the O and methine C atoms deviating from the plane of the other four atoms.
