Rapid and High-Yield Electrosynthesis of Benzisoxazole and Some Derivatives

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).

Formation of 2-sulphamoylacetylphenol from zonisamide under aerobic conditions in rat liver microsomes

1. The antiepileptic agent zonisamide, 1,2-benzisoxazole-3-methanesulphonamide, was metabolized reductively to 2-sulphamoyl-acetylphenol (SMAP) not only under anaerobic conditions but also under aerobic conditions in liver microsomes of rat pretreated with phenobarbital or dexamethasone. 2. NADPH was required for the formation of SMAP from zonisamide under aerobic conditions. In addition, the reductive metabolism of zonisamide under these conditions was substantially inhibited by carbon monoxide, ketoconazole, and cimetidine, known inhibitors of cytochrome P450. 3. The formation of SMAP under aerobic conditions in liver microsomes was increased by pretreatment of rat with triacetyloleandomycin (TAO) and was increased by the treatment of the microsomes with ferricyanide. 4. These results imply that zonisamide is metabolized reductively to SMAP by a cytochrome P450 belonging to the 3A subfamily under aerobic conditions as well as anaerobic conditions.

RATE OF DECARBOXYLATION OF BENZISOXAZOLE-3-CARBOXYLATE IONS AS A PROBE OF SOLVATION IN BIOLOGICAL AND OTHER MEDIA

The influence of solvent donor-acceptor properties and polarity on the rates of decarboxylation of benzisoxazole-3-carboxylate ions is analyzed with the unified solvation model. When the dissolved species is a separated ion pair, solvent polarity decreases the rate. When an equilibrium exists between an ion pair and the dissociated ion pair, solvent polarity and donor strength increase the rate by increasing the extent of dissociation. Hydrogen bonding to the carboxylate functionality causes a significant decrease in rate. When using this probe to measure the solvation properties of solvents, micelles, polymers, or biological assemblies, these different effects must be sorted out to interpret the influence of the medium on the observed rate. The unified solvation model provides a means of sorting out these various contributions.

Synthesis and Study of Oxadisilole-Fused Benzisoxazoles or Naphthisoxazoles

Oxadisilole-fused benzisoxazoles or naphthisoxazoles were obtained through 1,3-dipolar cycloaddition of arynes with nitrile oxides in good yields at room temperature. Key to the procedure is the simultaneous in situ generation of reactive nitrile oxides from arenecarbohydroximoyl chlorides and aryne reactants from benzobis(oxadisilole) or 2,3-naphthoxadisilole. One oxadisilole-fused benzisoxazole is a new precursor of a benzyne formed by a phenyliodination/fluoride-induced elimination protocol. By using this benzyne, cycloadducts were synthesized in good yields. The de-oxadisilole reaction of some of the oxadisilole-fused benzisoxazoles could be easily conducted with a 1.0 M solution of tetrabutylammonium fluoride in THF at room temperature.

Influence of inter- and intramolecular hydrogen bonding on Kemp decarboxylations from QM/MM simulations

The Kemp decarboxylation reaction for benzisoxazole-3-carboxylic acid derivatives has been investigated using QM/MM calculations in protic and dipolar aprotic solvents. Aprotic solvents have been shown to accelerate the rates of reaction by 7-8 orders of magnitude over water; however, the inclusion of an internal hydrogen bond effectively inhibits the reaction with near solvent independence. The effects of solvation and intramolecular hydrogen bonding on the reactants, transition structures, and the rate of reaction are elucidated using two-dimensional potentials of mean force (PMF) derived from free energy perturbation calculations in Monte Carlo simulations (MC/FEP). Free energies of activation in six solvents have been computed to be in close agreement with experiment. Solute-solvent interaction energies show that poorer solvation of the reactant anion in the dipolar aprotic solvents is primarily responsible for the observed rate enhancements over protic media. In addition, a discrepancy for the experimental rate in chloroform has been studied in detail with the conclusion that ion-pairing between the reactant anion and tetramethylguanidinium counterion is responsible for the anomalously slow reaction rate. The overall quantitative success of the computations supports the present QM/MM/MC approach, which features PDDG/ PM3 as the QM method.

Aspects of the aromaticity of anthranil

The standard (pdegrees = 0.1 MPa) molar enthalpy of formation of liquid anthranil was measured at T = 298.15 K by static bomb calorimetry and the standard molar enthalpy of vaporization at T = 298.15 K was obtained using Calvet microcalorimetry. These values were used to derive the standard molar enthalpy of formation of anthranil in the gaseous phase. Thermochemical and quantum chemical comparisons were made to interrelate anthranil and its isomers, 1,2-benzisoxazole, benzoxazole and 2-cyanophenol, and the monocyclic heterocycles, isoxazole and oxazole. Comparisons with benzofurazan and isobenzofuran were also made. Additionally nucleus-independent chemical shifts were used as an aromaticity index. (C) Wiley-VCH Verlag GmbH & Co.

Bacterial Degradation of Risperidone and Paliperidone in Decomposing Blood

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high-performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37 degrees C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7 degrees C, but degraded significantly in inoculated blood at 20 and 37 degrees C. Complete loss occurred within 2 days when incubated at 37 degrees C. The benzisoxazole-cleaved degradation products for both drugs were identified as 2-hydroxybenzoyl-risperidone and 2-hydroxybenzoyl-paliperidone utilizing liquid chromatography quadrupole-time-of-flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.
