In the title complex, [Ir(C11H8N)2(C6H5N2O)], the octa-hedrally coordinated Ir(III) atom is bonded to two 2-(pyridin-2-yl)phenyl ligands, through two phenyl C and two pydidine N atoms, and to one pyridine-2-aldoxime ligand through a pyridine N and an oxime N atom. The oxime O atom of the aldoxime unit forms inter-molecular C-H⋯O hydrogen bonds, which result in a two-dimensional hydrogen-bonded ...

[structure: see text] We synthesized estrone oximes as chemical inducers of protein heterodimerization (CIDs). Estrone-17-(O-carboxymethyl)oxime coupled to biotinamidocaproic acid via N,N'-dimethylhexane-1,6-diamine efficiently heterodimerizes estrogen receptors (ERs) and streptavidin Y43A in yeast three hybrid systems, activating gene expression over 100-fold at 10 microM. Related hexane-1,6-d...

In this study, in order to find novel biologically active pyrazole oxime derivatives, twenty-eight new pyrazole oxime compounds containing a substituted isoxazole ring were synthesized and evaluated for their acaricidaland insecticidal activities. Bioassays exhibited that some target compounds indicated good acaricidal and insecticidal activities against Tetranychus cinnabarinus, Aphis medicagi...

The title compound, C(10)H(10)N(2)O(2), was synthesized by the reaction of the oxime of 2-acetyl-pyridine and 3-bromo-propanoyl chloride in the presence of triethyl-amine. The mol-ecule adopts a nearly planar chain-extended conformation with the oxime group in a trans and the acryloyl group in an s-cis conformation. This conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond. The ...

The synthesis of a two-stage photobase generator (PBG) based on photoinduced aromatization is described. This material was designed for use in resolution-enhanced photolithography. Computer modeling predicts that a delay in the onset of base generation can lead to improved image quality. This delay can be realized by a PBG that must undergo two sequential photoreactions for each molecule of bas...

A variety of novel natural products with significant bioactivities are produced by the basidiomycete Boreostereum vibrans. In the present study, we describe 16 novel natural oximes and oxime esters with a vibralactone backbone, vibralactoximes, which were isolated from the scale-up fermentation broth of B. vibrans. Their structures were determined through extensive spectroscopic analyses. These...

In the title compound, C(7)H(6)N(2)O(3), the planes containing the CNO and ONO atoms subtend dihedral angles of 5.47 (5) and 8.31 (5)°, respectively, with the benzene ring. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers with an R(2) (2)(6) graph-set motif.

The title compound, C(28)H(28)N(2)O(4), was synthesized by the reaction of 2-acetyl-1-naphthol with 1,4-bis-(amino-oxy)butane in ethanol. The molecule, which lies about an inversion centre, adopts a linear structure, in which the oxime groups and naphthalene ring systems assume an anti conformation. The intra-molecular inter-planar distance between parallel naphthalene rings is 1.054 (3) Å. Int...

In the title compound, C(8)H(11)N(3)O(2), the oxime and the acetyl groups adopt a transoid conformation, while the pyrazole H atom is localized in the proximity of the acetyl group and is cis with respect to the acetyl O atom. In the crystal, dimers are formed as the result of hydrogen-bonding inter-actions involving the pyrazole NH group of one mol-ecule and the carbonyl O atom of another. The...
