An isoxazole-based polymeric co-ordination network incorporating a helical Ag(I)-S structural motif

An isoxazole-based ligand 2 bearing a thioether side arm in the 5-position of the heterocycle forms a polymeric coordination network with Ag(ClO4) (space group Aba2), in which the ligand is coordinated to three different silver ions via the ring N and the bridging thioether-S. The resulting layer structure consists of infinite Ag(I)-S helices linked by the isoxazole moieties, with the latter being stacked above each other. A related complex 2 . AuCl (space group C2/c) features linear S-Au-Cl units associated by weak d(10)-d(10) interactions, while the isoxazole nucleus remains uncoordinated. The solid state structures are compared to those of related isothiazole complexes. (C) 1999 Elsevier Science Ltd. All rights reserved.

Simple primary amine catalyzed aerobic reductive ring-cleavage of isoxazole motif

A clean and highly efficient catalytic aerobic reductive ring-cleavage of 3-methylanthra[1,2-c]isoxazole-6,11-dione to 1-amino-2-acetylanthraquinone was performed using simple organic amines as organocatalysts and water as a green reaction medium. This method provides a new clean transformation of isoxazole-containing compounds to the corresponding ortho-amino ketones. The catalytic performance of various organic amines was carefully screened, and simple organic primary amines were found to be promising practical catalysts with outstanding catalytic performance. Isopropylamine as the organocatalyst gave 97.2% conversion of 3-methylanthra[1,2-c]isoxazole-6,11-dione, with 97.2% selectivity to 1-amino-2-acetylanthraquinone, in the presence of oxygen only, using 1 equiv. of hydrazine hydrate at room temperature for 3 h. A possible mechanism is also proposed. (C) 2015, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V. All rights reserved.

Direct versus Indirect Photodissociation of Isoxazole from Product Branching: A Chirped-Pulse Fourier Transform mm-Wave Spectroscopy/Pulsed Uniform Flow Investigation

The UV photodissociation of isoxazole (c-C3H3NO) is studied in this work by chirped-pulse Fourier transform mm-wave spectroscopy in a pulsed uniform Laval flow. This approach offers a number of advantages over traditional spectroscopic detection methods due to its broadband, sub-MHz resolution, and fast-acquisition capabilities. In coupling this technique with a quasi-uniform Laval flow, we are able to obtain product branching fractions in the 193 nm photodissociation of isoxazole. Five dissociation channels are explored through direct detection of seven different photoproducts. These species and their respective branching fractions (%) include the following: HCN (53.8 +/- 1.7), CH3CN (23.4 +/- 6.8), HCO (9.5 +/- 2.3), CH2CN (7.8 +/- 2.9), CH2CO (3.8 +/- 0.9), HCCCN (0.9 +/- 0.2), and HNC (0.8 +/- 0.2). Guided by previous electronic structure and dynamics simulations, we are able to elucidate the dissociation dynamics that govern the final product branching fractions observed in this work, which differ significantly from previous reports on the thermal decomposition of isoxazole. Interestingly, both direct and indirect dynamics contribute to its dissociation, and clear signatures of both are manifested in the relative branching ratios obtained. Consistent with previous studies on the unimolecular dissociation of isoxazole, our findings also suggest the importance of the open-shell singlet diradicaloid species vinylnitrene in the dissociation dynamics, regardless of the initially populated excited state. This work, taken together with previous investigations, provides a global picture of the complex dissociation pathways involved in the photodissociation of isoxazole.

Single/double 1,2,3-triazoles bearing isoxazole ether were synthesized by click reaction starting from substituted isoxazolyl alkyne compounds and substituted benzyl azide compounds or neopentylglycol diazide in the presence of copper(I) that in-situ generated. Herein, the effect of different catalysts on the yield was researched by conventional method, and the optimal catalyst was selected. The structures of all the synthesized compounds were confirmed by MS, FTIR, H-1 and C-13 NMR spectroscopies. Moreover, the crystal structure of 5-{[(1-benzyl-1H-1,2,3-triazol-4-yl) methoxy] methyl}-3-(4-fluorophenyl) isoxazole(2h) was determined.

Rapid and High-Yield Electrosynthesis of Benzisoxazole and Some Derivatives

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).
