Synthesis and fungicidal activities of [2-(2,5-dimethylphenoxymethyl)-alpha-methoxyiminobenzyl]-isoxazole derivatives

A series of [2-(2, 5-dimethylphenoxymethyl)-alpha-methoxyiminobenzyl]isoxazole derivatives were synthesized and their fungicidal activities against crop diseases were assessed. Our studies of the structure-activity relationships revealed that fungicidal activities against cucumber powdery mildew and wheat powdery mildew were the strongest when the isoxazole moiety was comprised of 4,5-dihydro-3-isoxazolyl, 3-isoxazolyl and 3-methyl-5-isoxazolyl groups. Of the two geometrical isomers at the oxime moiety, the E-isomers of non-substituted isoxazole derivatives were more active than the Z-isomers, On the other hand, the Z-isomers of methyl-substituted isoxazole derivatives were more active than the E-isomers. Further, [2-(2,5-dimethylphenoxymethyl)-alpha-methoxyiminobenzyl] isoxazole derivatives exhibited highly potent respiratory inhibition.

Synthesis and liquid crystalline properties of 3-substituted pentane-2,4-dione, pyrazole and isoxazole derivatives

The gamma-substituted beta-diketonate 2,4-dioxo-3-pentyl 4-[4-(n-octyloxy)cinnamoyl]oxybenzoate 1 and its pyrazole and isoxazole derivatives (2 and 3 respectively) have been synthesized and characterized by the spectroscopic methods and elemental analysis. The mesogenic properties of these compounds have been studied by polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). A monotropic nematic mesophase was observed for the beta-diketonate 1, in contrast, the pyrazole 2 displays an enantiotropic smectic A and isoxazole 3 exhibits an enantiotropic nematic mesophase. The relationship between the structure and liquid crystalline properties has also been discussed.

A number of new isoxazole coupled pyrimido[4,5-c]isoquinolines has been synthesized in good to excellent yields by the one pot method. The Cu(I)-catalyzed cycloaddition reaction between the terminal alkyne 4 and various aldehydes has led to nitrile oxides.

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-#).
