Synthesis and the effects of substitution upon photochromic diarylethenes bearing an isoxazole moiety

A new class of unsymmetrical photochromic diarylethenes bearing an isoxazole moiety was synthesized and the effects of substitution on their optical and electrochemical properties were investigated systematically. Each of the compounds exhibited remarkable photochromism and functioned as a fluorescent photoswitch both in solution and in poly(methyl methacrylate) films. The electron-donating substituents effectively shifted the absorption maximum and the emission peak to a longer wavelength direction, while the electron-withdrawing substituents notably enhanced the fluorescent quantum yields and oxidation onsets of these diarylethene derivatives. As compared to the unsubstituted parent diarylethene, introduction of the electron-donating/withdrawing substituents could efficiently modulate the optical and electrochemical properties of the diarylethenes bearing an isoxazole moiety. All results indicated that the isoxazole moiety and the substitution effects played a very important role during the process of photochromic reaction for these diarylethene derivatives.

Synthesis of 3-Nitroisoxazoles via Copper Acetate-Mediated Reaction of Benzaldehydes with Nitromethane

A copper acetate-mediated reaction of benzaldehydes with nitromethane to synthesis of 3-nitroisoxazoles is reported. A variety of nitro-aryl-disubstituted isoxazole derivatives can be prepared in moderate to good yields with benign functional group tolerance. This protocol is successfully applied in gram-scale reaction. Preliminary mechanistic studies reveal that the aldehyde provided one carbon atom for the isoxazole ring, and nitromethane provided two carbon atoms and one nitrogen atom for the isoxazole ring. In this protocol, the C-O-N unit in the final isoxazole ring is formed from the rearrangement of nitromethane.

Unusual Retention of Isoxazole Ring under the Influence of 3-(Substituted nitrophenyl)-2-Isoxazoline during Catalytic Hydrogenation of Isoxazoline-Substituted Isoxazole Systems

The cleavage of the isoxazole ring during the Raney-Ni-promoted catalytic hydrogenation is prevented under the influence of 3-(substituted nitrophenyl)-2-isoxazoline in isoxazoline-substituted isoxazole systems, produced via 1,3-dipolar cycloaddition either on the Baylis-Hillman derivatives or Grignard products. Unexpectedly, the hydrogenations in these diastereomeric compounds were observed to exclusively yield products, wherein the methoxycarbonyl and the hydroxyl or the acetyl groups exist syn to each other.

Kinetics of hydrolysis of five-membered C-nitroheterocycles: pyrazole, imidazole, 1,2,4-triazole, and isoxazole derivatives

Alkaline hydrolysis of mono- and dinitro derivatives of five-membered heterocycles, viz., pyrazole, imidazole, 1,2,4-triazole, and isoxazole, is accompanied by the elimination of the nitro group in the form of a nitrite anion. The hydrolysis kinetics was studied by the polarographic and photometric methods. The experimentally determined hydrolysis rate constants depend on the nature of the heterocycle. A possible mechanism for hydrolytic transformations of the compounds under study was proposed on the basis of the calculated thermodynamic parameters of the reaction (Delta G(#), Delta H-#, Delta S-#).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Theoretical investigation of gold(I)-catalyzed intramolecular SEAr in isoxazole derivatives: Mechanisms, origin of regioselectivity, and role of hydrogen acceptor

A detailed theoretical study on the mechanism and regioselectivity of the Au(I)-catalyzed intramolecular electrophilic aromatic substitution (SEAr) in 4-substituted isoxazole derivatives is reported, using two model substrates, 4-(1-methylpropargyloxy)isoxazole (Series A) and 4-(1-methyl propargylamino)isoxazole (Series B). The obtained theoretical data reveal similar energy profiles in both series for the 6 endo dig heteroatom-assisted SEAr to form an alkenyl Au(I) intermediate. Then, in the series A, the 1,3-H-shift assisted by the 4-propargyloxyisoxazole leads to a final product and the catalyst regeneration. In contrast, in the series B, the elimination of proton by N-phenylbenzaldimine additive results in an iminium cation and dihydropyridine. In the next step, a hydride from dihydropyridine is accepted by the iminium cation to furnish pyridinium and N-benzylidenebenzenaminium species. Subsequently, protodeauration leads to a final product and N-phenylbenzylamine along with the catalyst regeneration. In the absence of N-phenylbenzaldimine additive, 4-(1-methylpropargylamino) isoxazole accepts the hydride instead of N-phenylbenzylamine and causes the consumption of the reactants, thus accounting for a low product yield. Furthermore, the regioselectivity and its origin as well as the rationalization of the deuterium labeling experiments are also examined and discussed in detail.
