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.

Liquid crystalline analogues of curcumin

Compounds that are modifications of curcumin were synthesised and their mesogenic properties were studied. The central keto-enolic ring in curcumin was replaced by either a pyrazole or an isoxazole ring. This gives compounds that can form liquid crystalline phases. When two alkoxy chains are attached to the molecule, nematic and lamellar phases appear; in the case of six alkoxy chains, a hexagonal columnar phase is created. The columnar phase is constructed from columns that in the cross-section have two molecules. The pyrazole derivatives in the columnar phase preserve N-H-N hydrogen bonding.

A Fast and Highly Efficient Protocol for Reductive Amination of Aromatic Aldehydes Using NaBH4 and Isoxazole Amines in an Ionic Liquid Medium

Reductive amination of aromatic aldehydes using NaBH4 and isoxazole amines is carried out in a Bronsted acidic ionic liquid 1-methylimidazolium tetrafluoroborate [(HMIm)BF4]. The ionic liquid plays dual roles of solvent as well as catalyst for the efficient transformation of aromatic aldehydes to heterocyclic substituted amines in excellent yields without any undesired side product formation. The newly synthesized compounds (3, 6 and 7) were characterized by IR, H-1 NMR and mass spectral techniques.

A series of novel isoxazole-containing neonicotinoids were synthesized from nitromethylene analogues and aromatic aldehydes in the presence of L-proline/K2CO3. Bioassays indicated that several synthesized compounds showed 40-70% mortality against brown planthopper (Nilaparvata lugens) under the concentration of 4 mg L-1, higher than that of imidacloprid (20%). Against cowpea aphid (Aphis craccivora), the best activity of title compounds reached 90% at the concentration of 20 mg L-1. (C) 2017 Published by Elsevier Ltd.

Synthesis of fluorinated triazole and isoxazole derivatives by electrochemical fluorination

Partially fluorinated triazole derivatives were synthesized through anodic fluorination of allcynes having arylthio group and following Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with benzyl azide. The other route toward the fluorinated triazoles, namely the anodic fluorination of triazole derivatives once prepared by advanced CuAAC of the alkyne and azide above was also investigated. It was shown that these two routes are mutually complementary methodology for the synthesis of new mono- and difluoromethyltriazole derivatives. Furthermore, Cu(I)-catalyzed isoxazole synthesis from fluorinated alkynes and imidoyl chloride was demonstrated. (C) 2016 Elsevier Ltd. All rights reserved.
