Vibrational assignment of isoxazole aided by rovibrational data and density functional theory

IR and Raman spectra of isoxazole and D(3)-isoxazole are reassigned with the aid of density functional theory calculations at the B3LYP/6-311+G(d,p) level. Harmonic wavenumber values of all non-CH stretch modes give an r.m.s. deviation from experimental values of 3 cm(-1) when they are uniformly scaled by 0.9818. Anharmonic values obtained using a second-order perturbative approach show an r.m.s. deviation of 7.6 cm(-1). Results of equal quality are obtained for D(3)-isoxazole. Predicted Raman and IR band strengths match experimental spectra very closely. Detailed re-examination of rovibrational constants and inertial defect data from high resolution IR spectra, in comparison with values from the anharmonic frequency calculation, provides confirmation of the vibrational assignments. ‘Dark state’ fundamentals nu(12) (900.2 cm(-1)) and nu(15) (866 cm(-1)) are detected through the perturbations they cause in nearby bands.

The high-resolution infrared spectrum of isoxazole vapor between 800 and 1700 cm(-1)

The Fourier transform gas-phase IR spectrum of isoxazole, C3H3NO, between 550 and 1700 cm(-1) was measured with a resolution of ca. 0.003 cm(-1). Ten fundamental bands in the region 800-1700 cm(-1) have been analyzed by the Watson Hamiltonian model to yield upper state spectroscopic constants. A number of local resonances have been identified in the bands and explained qualitatively, and the unobserved nu(14)(A) fundamental band has been located at 897.5(5) cm(-1) from its perturbation effects on the neighboring fundamentals.

We report here a simple entry into naphtho[2,3-d]isoxazole-4,9-dione system containing a EWG in position 3 using the readily available 2,3-dichloro-1,4-naphthoquinone and nitromethyl derivatives in the presence of base. Antifungal activity of synthesised naphthoquinones was evaluated against ATCC and PYCC reference strains of Candida. The results suggest that the naphtho[2,3-d]isoxazole-4,9-dione scaffold has the potential to be developed into novel and safe therapeutic antifungal agents. (C) 2009 Elsevier Ltd.

3-(Arylthiomethyl)isoxazole-4,5-dicarboxamides: Chemoselective Nucleophilic Chemistry and Insecticidal Activity

A collection of 91 3-(arylthiomethyl)isoxazole-4,5-dicarboxamides was prepared starting from dimethyl 3-(chloromethyl)isoxazole-4,5-dicarboxylate. The thioether moieties in these compounds were subsequently oxidized to give the corresponding 3-(arylsulfonylmethyl)isoxazole-4,5-dicarboxamides. By carefully controlling stoichiometry and reaction conditions, the C4 and C5 carbomethoxy groups could be differentially derivatized to carboxamides. A total of 182 trisubstituted isoxazoles are reported and deposited in the National Institutes of Health Molecular Repository; an 80 compound subset was evaluated for insecticidal activity.

Theoretical study of thermal decomposition mechanisms of isoxazole

Density functional theory and ab initio calculations were carried out to investigate two probable unimolecular decomposition channels of isoxazole. The calculated structural parameters, dipole moment, and vibrational frequencies of isoxazole are in good agreement with available experimental data. Relative energies of transition states and equilibrium structures evaluated at MP4 and QCISD(T) levels of theory at B3LYP/6-31G** structures indicate that CO and CH3CN, major products of isoxazole thermal decomposition in the temperature range 850-1100 K, are unlikely produced via the mechanism proposed in the experimental and previous theoretical studies. Instead, the mechanism proposed in the current study, isoxazole –> NCCH2CHO –> CH3CN + CO, is more likely the main unimolecular decomposition channel. The mechanism proposed in the experimental study was shown to have a higher activation barrier and is likely responsible for the formation of HCN and H2CCO, minor products of isoxazole decomposition.

Synthesis and characterization of a new series of liquid crystal compounds derived from isoxazoles

Two homologous series of phenylisoxazoles derived from 3-[4-(4-trans-n-heptylcyclohexyl)phenyl]-5-(4-alkoxyphenyl)isoxazole and 3-[4-(4-trans-n-heptylcyclohexyl)phenyl]-5-(5-nalkylthiophene)isoxazole have been synthesized. The liquid crystal compounds obtained were characterized by NMR, differential scanning calorimetry (DSC), and optical polarized microscopy (POM). The properties of the liquid crystalline phase were investigated as a function of terminal units and type of core aromatic rings. It was found that (1) the phase transition temperature decreased with the change of core aromatic rings from phenyl for thienyl, and (2) the types of mesophase formed by these compounds do not depend on the length of the terminal chain. Thermotropic nematic and smectic phases were observed.
