Desoxyhemigossypol 6-methyl ether
THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48 (2)°. In the crystal, O-H⋯O hydrogen bonds be...
متن کاملTailoring the Characteristics of Poly (phenylene-ether-ether) sulfone Membrane for Efficient Glycerol/Biodiesel Separation
Poly (phenylene-ether-ether) sulfone membrane was fabricated and characterized by efficient glycerol/biodiesel separation produced from waste cooking oils trans-esterification. The membrane preparation was processed by phase inversion technique. The morphology, Physico-chemical properties and separation behavior of membranes were studied at various PPEES concentration. A uniform surface was...
متن کاملSynthesis of a 2,2'-bipyridyl functionalized oligovinylene-phenylene using Heck and Horner-Wadsworth-Emmons reactions and X-ray crystal structure of E-(4-(4-bromostyryl)phenyl)(methyl)sulfane.
The synthesis of a new 2,2'-bipyridyl functionalized oligovinylenephenylene (OVP-5) containing a methyl protected thiol using Heck coupling and the Horner-Wadsworth-Emmons reaction and is described. A key step involving a diisopropylcarbodiimide promoted dehydration of a stable β-hydroxyphosphonate intermediate was identified. The structure of precursor E-(4-(4-bromostyryl)phenyl)(methyl)sulfan...
متن کاملBis(3-methoxy-6-methyl-2-pyridyl) ether
In the mol-ecule of the title compound, C(14)H(16)N(2)O(3), the dihedral angle between the pyridyl rings is 87.74 (3)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into infinite zigzag chains.
متن کاملBis[4-(chloroacetyl)phenyl] ether
The title compound, C(16)H(12)Cl(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. The dihedral angles between the planes of the benzene rings in the two independent mol-ecules are 68.65 (2) and 68.47 (3)°. The short distance of 3.899 (5) Å between the centroids of the benzene rings of neighbouring mol-ecules indicate π-π inter-actions. The crystal structure is stabil...
