Crystal structure of 1,3-bis[(E)-benzylideneamino]propan-2-ol
In the title compound, C17H18N2O, the central carbon atom with the OH substituent and one of the (E)-benzyl-idene-amino substituents are disordered over two sets of sites with occupancies of 0.851 (4) and 0.149 (4). The relative positions of the two disorder components is equivalent to a rotation of approximately 60° about the C-N single bond. In the crystal, the mol-ecules are held together by...
متن کاملCrystal structure of 1,4,5,6,7,8,9,10,11,12,13-undecahydrocyclododeca[c]pyrazol-3-ol
The title compound, C13H22N2O, crystallized as a pyrazolol tautomer. The 12-membered macrocycle has a distorted chair conformation. In the crystal, mol-ecules are linked via pairs of O-H⋯N hydrogen bonds, forming inversion dimers. The dimers are linked via N-H⋯π and C-H⋯π inter-actions, forming slabs parallel to the bc plane.
متن کاملCrystal structure of naltrexone chloride solvates with ethanol, propan-2-ol, and 2-methylpropan-2-ol
Naltrexone [systematic name: 17-(cyclo-propyl-meth-yl)-3,14-di-hydroxy-4,5α-epoxymorphinan-6-one] is an opioid receptor competitive antagonist that has been widely used to prevent relapse in opioid- and alcohol-dependent subjects. Its chloride salt forms non-isomorphic solvates with ethanol (C20H24NO4+·Cl-·C2H5OH) (I), propan-2-ol (C20H24NO4+·Cl-·C3H7OH) (II), and 2-methyl-propan-2-ol (C20H24NO...
متن کامل3α-Hydroxy-ent-atis-16-en-14-one
The title compound, C(20)H(30)O(2), is an ent-atisane diterpenoid which was isolated from the roots of Euphorbia kansuensis. The mol-ecule contains five six-membered rings, among which three six-membered rings of the bicyclo-[2.2.2]octane unit adopt boat conformations and two cyclo-hexane rings adopt chair conformations. In the crystal structure, mol-ecules are connected by inter-molecular O-H⋯...
متن کاملPositive Relationship between Menstrual Synchrony and Ability to Smell 5α-Androst-16-en-3α-ol
To explore the possibility that compounds which were identified as pheromones in experimental animals mediate human menstrual synchrony, we examined the relationship between menstrual synchrony and the ability to smell putative pheromones, 5α-androst-16-en-3α-ol (3α-androstenol) and 5α-androst-16-en-3-one (5α-androstenone). When we examined menstrual synchrony among 64 women living together in ...
