The mol-ecule of O-acetyl-swietenolide, C(29)H(36)O(9), isolated from the seeds of Swietenia macrophylla, features four six-membered rings connected together in the shape of a bowl; one of the inner rings adopts a twisted chair conformation owing to the C=C double bond. The furyl substitutent is connected to an outer ring, and it points away from the bowl cavity. The hy-droxy group is connected...

In the title mol-ecule, C(15)H(14)O(4), the benzene and furyl rings are inclined to each other with a dihedral angle of 41.5 (1)°. An intra-molecular C-H⋯O hydrogen-bond inter-action generates an S(5) ring motif. In the crystal structure, mol-ecules are stacked along the b axis and the crystal packing is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions. In addition, π-π stacking inte...

Mixed ligand complexes of bivalent metal ions, viz; Co(II), Ni(II), Cu(II) and Zn(II) of the composition (ML1L2) in 1:1:1 molar ratio, (where L1=diphenylamine-2-mercapto-2’-carboxylic acid (DPMC) and L2=2-furyl glyoxalanthranilic acid (FGAA) have been synthesized and characterized by repeated melting point determination, elemental analyses, IR, H-NMR, magnetic susceptibility measurements and el...

Zaragozic acid A analogues are produced by an unidentified sterile fungus when it is exogenously supplied with 2-thiophenecarboxylic acid, 3-thiophenecarboxylic acid, 2-furoic acid, 2-fluorobenzoic acid, 3-fluorobenzoic acid, or 4-fluorobenzoic acid. The analogues carry 2-thiophenyl, 3-thiophenyl, 2-furyl, o-fluorophenyl, m-fluorophenyl, or p-fluorophenyl group, respectively, at C-6' of the C-1...

In the title compound, C(13)H(9)Br(2)NO(4), the phenyl and 2-nitro-furan rings are linked by a 2,3-dibromo-propanal group, six atoms of which, including a furyl C atom, are disordered over two positions with a site-occupancy ratio of 0.733 (11):0.267 (11). The dihedral angle between the furan [maximum deviation = 0.028 (4) Å] and phenyl rings in the major component is 16.9 (3)°. In the minor co...

The compound 2-furyl-1-nitroethene (G-0) has been tested to determine its ability to induce clastogenic or aneugenic effects in vivo, through the induction of micronucleated polychromatic erythrocytes (MNPCE) in mouse bone marrow. Groups of five CD-1 male mice were administered once intraperitoneally at a dose range of 5-20 mg/kg and bone marrow was sampled at 24 and 48 h after the treatment. G...

The substitution of secondary propargylic phosphates ROP(O)(OEt)2 where R = [Ph(CH2)2]C(H)(C≡CTMS)] Ph(CH2)2CH(OP(O)(OEt)2)(C≡CTMS) with copper reagents derived from PhLi and salts such as CuCl, CuCN, Cu(acac)2 was studied to establish an ArLi-based reagent system. Among the prepared, PhLi/CuCl (2:1) showed 98% α regioselectivity (rs), while PhLi/Cu(acac)2 γ selective (>99% rs). prepared in ...

In the title complex, [CdI(2)(C(16)H(12)N(2)O(2))(2)], the Cd(II) atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-fur-yl)-1-(2-furyl-meth-yl)-1H-benzimidazole ligands and two I atoms in a distorted tetra-hedral configuration. The benzimidazole rings in adjacent mol-ecules are parallel, with an average inter-planar distance of 3.486 Å....
