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.

FACILE AND CONVENIENT SYNTHESIS OF NEW ISOXAZOLO[5,4-b]PYRIDINE, PYRROLO[3,2-d]ISOXAZOLE, ISOXAZOLO[5,4-b]AZEPINE-4,7-DIONE AND ISOXAZOLE DERIVATIVES WITH POTENTIAL ANTICANCER ACTIVITY

The readily available 3-methylisoxazol-5-amine (1) has been used as a key intermediate for the synthesis of isoxazolo[5,4-b]pyridine, pyrrolo[3,2-d]isoxazole, isoxazolo[5,4-b]azepine-4,7-dione and isoxazole derivatives via its reactions with some chemical reagents. Sixteen compounds were designed to study their cytotoxic properties against three human cell lines: colorectal carcinoma (HCT-116), prostate cancer (PC3) and normal lung fibroblast (WI-38), using the MTT colorimetric assay. 5-Fluorouracil, a well-known anticancer drug, was used for comparison. Among the tested candidates, pyrrolo[3,2-d]isoxazole 5 and isoxazole derivatives 11-14 showed the highest activity against the tested cancer cell lines with good selectivity by their lower toxicity against normal cells.

One-pot three-component synthesis of isoxazole using ZSM-5 as a heterogeneous catalyst

A mild and convenient route for the synthesis of isoxazole derivatives has been developed using ZSM-5 as a heterogeneous catalyst. The reaction was carried out under a solvent-free condition to afford the desired products in good yields. A variety of functional groups was tolerated under the reaction conditions employed. Moreover, the heterogeneous catalyst (ZSM-5) was recovered and reused several times without significant loss of its catalytic activity.

Synthesis and characterization of selected fused isoxazole and pyrazole derivatives and their antimicrobial activity

New potent antibacterials, fused isoxazole and pyrazole derivatives, were synthesized using 5,5-dimethylcyclohexane-1,3-dione (1) and 3-[(4-chlorobenzylidene)amino]-2-thioxoimidazolidin-4-one (2) as synthons. Aromatic aldehydes on condensation with I and 2 gave 2-arylidene-5,5-dimethylcyclohexane-1,3-dione (3) and 5-arylidene-3-[(4-chlorobenzylidene)amino]-2-thioxoimidazolidin-4-one (4), respectively. Compounds 3 and 4 were forced to undergo heterocyclization reaction with nucleophilic reagents to give the title compounds. The newly synthesized heterocyles (5-8) were characterized based on their chemical properties and spectroscopic data, and were found to inhibit Staphylococcus aureus and Corynebacterium diphtheriae.

Synthesis of Isoxazole- and Oxazole-4-carboxylic Acids Derivatives by Controlled Isoxazole-Azirine-Isoxazole/Oxazole Isomerization

The first synthesis of isoxazole-4-carboxylic acid derivatives by domino isoxazole-isoxazole isomerization is reported. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxy-/5-aminoisoxazoles (dioxane, 105 degrees C) leads to the formation of isoxazole-4-carboxylic esters and amides in good yields. 4-Formyl-5-methoxyisoxazoles give methyl oxazole-4-carboxylates under the same reaction conditions. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxyisoxazoles under milder conditions (MeCN, 50 degrees C) allows the preparation of transient 2-acyl-2-(methoxycarbonyl)-2H-azirines. The azirines isomerize quantitatively either into isoxazoles under catalytic conditions (dioxane, 105 degrees C) or into oxazoles under noncatalytic thermolysis (o-dichlorobenzene, 170 degrees C). The mechanism of the isomerization and dependence of the reaction routes on substituents at starting isoxazole core and reaction conditions are discussed on the basis of DFT calculations.
