Utility of Nitrogen Extrusion of Azido Complexes for the Synthesis of Nitriles, Benzoxazoles, and Benzisoxazoles

The utility of the nitrogen extrusion reaction of azido complexes, generated in situ from the corresponding aldehydes or ketones with TMSN3 in the presence of ZrCl4 or TfOH, has been described. These azido complexes could undergo three different pathways, depending on the substrates. First, azido methanolate complexes or imine diazonium ions could lead to benzisoxazole products via an intramolecular nucleophilic substitution. Second, imine diazonium ions could also undergo either the elimination of proton to provide nitrile products in good to excellent yields or an aryl migration, followed by an intramolecular nucleophilic addition, to give benzoxazole products in good yields.

Latent photochromism (pseudothermochromism) and photofatigue of crystalline 2-(2 ‘,4 ‘-dinitrobenzyl)pyridine

Along with the metastable 2-(2,4′-dinitrophenylmethylidene)-1,2-dihydropyridine (NH) and the unstable 6-aci-nitro-2-nitro-5-(2-pyridylmethylene)-1,3-cyclohexadiene (OH), the stable form of 2-(2′,4′-dinitrobenzyl)pyridine (DNBP), CH, is photochemically converted into small amounts of 1,2-bis(2′,4-dinitrophenyl)-1,2-bis(2′-pyridyl)ethane, trans-bis[5-nitro-2-(pyridine-2-carbonyl)phenyl]diazene N-oxide, 6-nitro-3-(2’-pyridyl)-2,1-benzisoxazole and 3-nitropyrido[1,2-b]quinolin-6-ium-11-olate. The latent photochromism of DNBP, as shown by x-ray analysis of the structures of the side-products and ESR/IR measurements, is attributed to open-shell reactions that are initiated by hydrogen photoabstraction and subsequent creation of two monoradicals, NH. and OH.. Large amounts of the radicals (ca 50% NH. and 70% OH) confined in the crystalline interior are persistent under ambient conditions. Through quasi-periodic reactions, the remaining radicals partially recover the ground-state isomers CH, NH and OH, or decay to the side-products, which results in crystalline photofatigue. Together with proton tunneling from the excited CH, the radical reactions represent dominant mechanism for the creation of NH and OH in the low-temperature regimes, but are successfully competed by the closed-shell reactions at higher temperatures. The precursor state, whose existence was assumed previously from transient absorption spectroscopy, may be identified as the radical OH.. The present work represents the first study of the photofatigue of a 2-(2,4-dinitrobenzyl)pyridine compound and extends the ‘classical’ mechanism of the photochromic reactions of nitrobenzylpyridines with a set of open-shell radical reaction routes.

Novel DNA Gyrase Inhibiting Spiropyrimidinetriones with a Benzisoxazole Scaffold: SAR and in Vivo Characterization

The compounds described herein with a spirocyclic architecture fused to a benzisoxazole ring represent a new class of antibacterial agents that operate by inhibition of DNA gyrase as corroborated in an enzyme assay and by the inhibition of precursor thymidine into DNA during cell growth. Activity resided in the configurationally lowest energy (2S,4R,4aR) diastereomer. Highly active compounds against Staphylococcus aureus had sufficiently high solubility, high plasma protein free fraction, and favorable pharmacokinetics to suggest that in vivo efficacy could be demonstrated, which was realized with compound (-)-1 in S. aureus mouse infection models. A high drug exposure NOEL on oral dosing in the rat suggested that a high therapeutic margin could be achieved. Importantly, (-)-1 was not cross-resistant with other DNA gyrase inhibitors such as fluoroquinolone and aminocoumarin antibacterials. Hence, this class shows considerable promise for the treatment of infections caused by multidrug resistant bacteria, including S. aureus.

Enantioselective Synthesis of beta-Amino Acid Derivatives Enabled by Ligand-Controlled Reversal of Hydrocupration Regiochemistry

A Cu-catalyzed enantioselective hydroamination of alpha,beta-unsaturated carbonyl compounds for the synthesis of beta-amino acid derivatives was achieved through ligand-controlled reversal of the hydrocupration regioselectivity. While the hydrocupration of alpha,beta-unsaturated carbonyl compounds to form alpha-cuprated species has been extensively investigated, we report herein that, in the presence of an appropriate ancillary chiral ligand, the opposite regiochemistry can be observed for cinnamic acid derivatives, leading to the delivery of the copper to the beta-position. This copper can react with an electrophilic aminating reagent, 1,2-benzisoxazole, to provide enantioenriched beta-amino acid derivatives, which are important building blocks for the synthesis of natural products and bioactive small molecules.

Gas phase ion chemistry of the heterocyclic isomers 3-methyl-1,2-benzisoxazole and 2-methyl-1,3-benzoxazole

Different mass spectrometric methods, stable isotope labeling, and theoretical calculations have allowed us to structurally characterize and differentiate the isomeric ion structures produced by the two heteroaromatic isomers 3-methyl-1,2-benzisoxazole and 2-methyl-1,3-benzoxazole. The low-energy collision induced dissociation spectra of their molecular ions show large differences. Although both of them produce abundant loss of CO, that involves a carbon atom of the benzene ring, the 2-methyl-1,3-benzoxazole also shows abundant [M-CHO](+) ions at m/z 104, the intensity of which is quite low in the case of its isomer 3-methyl-1,2-benziscxazole. In addition, MS/MS measurements of fragment ions show characteristic differences that allow distinction among the isomers depending on the original arrangement of the atoms in the five-membered ring. Theoretical ab initio calculations have allowed to determine chemico-physical properties of different ions and to propose a rationalization of the decomposition pathways followed by the two benz(is)oxazole isomers.

Benzisoxazole: a privileged scaffold for medicinal chemistry

The benzisoxazole analogs represent one of the privileged structures in medicinal chemistry and there has been an increasing number of studies on benzisoxazole-containing compounds. The unique benzisoxazole scaffold also exhibits an impressive potential as antimicrobial, anticancer, anti-inflammatory, anti-glycation agents and so on. This review examines the state of the art in medicinal chemistry as it relates to the comprehensive and general summary of the different benzisoxazole analogs, their use as starting building blocks of multifarious architectures on scales sufficient to drive human drug trials. The number of reports describing benzisoxazole-containing highly active compounds leads to the expectation that this scaffold will further emerge as a potential candidate in the field of drug discovery.

Clinical pharmacology and therapeutic drug monitoring of zonisamide

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) is a new antiepileptic drug developed in Japan. This compound is insoluble in water, and it is available in tablet and powder form. In experimental animals, this compound has been found to have a strong inhibitory effect on convulsions of cortical origin because it suppresses focal spiking and the spread of secondary generalized seizures. In humans, a series of double-blind, placebo-controlled studies revealed the efficacy of zonisamide for patients with refractory partial seizures and for selected patients with infantile spasms. Its antiepileptic mechanism of action remains unclear, but it is likely to involve blockade of both sodium and T-type calcium channels. Oral bioavailability of zonisamide is excellent in healthy human volunteers. Zonisamide is slowly absorbed and has a mean t(max) of 5 to 6 hours. Almost 100% of it is absorbed; there is no difference in bioavailability between tablets and powder. Zonisamide concentrations are highest in erythrocytes and then in whole blood and plasma. It is approximately 40% to 60% bound to plasma proteins, primarily albumin. Its volume distribution is 0.9 to 1.4 L/kg. In adults, the elimination half-life is between 50 and 62 hours, and it takes as long as 2 weeks to reach steady state. The dose-serum level correlation is linear up to doses of 10 to 15 mg/kg per day, and the therapeutic range is 10 to 40 mu g/ml. However, the relationship between serum zonisamide levels, clinical response, and adverse effects appears weak. Concurrent enzyme-inducing anticonvulsants such as phenytoin, carbamazepine, or barbiturates stimulate zonisamide metabolism and decrease serum zonisamide levels at steady state. Although zonisamide has been reported to increase the serum levels of phenytoin and carbamazepine in some patients, the interactions of zonisamide with other antiepileptic drugs seem to be of minor clinical relevance. A pilot study of zonisamide suppositories revealed that it is beneficial for patients with neurologic disorders in whom antiepileptic drugs cannot be administered by mouth.

Reformulating a Pharmacophore for 5-HT2A Serotonin Receptor Antagonists

Several pharmacophore models have been proposed for 5-HT2A serotonin receptor antagonists. These typically consist of two aromatic/hydrophobic moieties separated by a given distance from each other, and from a basic amine. Although specified distances might vary, the models are relatively similar in their general construction. Because our preliminary data indicated that two aromatic (hydrophobic) moieties might not be required for such action, we deconstructed the serotonin-dopamine antipsychotic agent risperidone (1) into four smaller structural fragments that were thoroughly examined in 5-HT2A receptor binding and functional (i.e., two-electrode voltage clamp (TEVC) and intracellular calcium release) assays. It was apparent that truncated risperidone analogues behaved as antagonists. In particular, 6-fluoro-3-(1-methylpiperidin-4-yl)benzisoxazole (4) displayed high affinity for 5-HT2A, receptors (K-i, of ca. 12 nM) relative to risperidone (K-i of ca. 5 nM) and behaved as a potent 5-HT2A serotonin receptor antagonist. These results suggest that multiple aromatic (hydrophobic) moieties are not essential for high-affinity 5-HT2A receptor binding and antagonist activity and that current pharmacophore models for such agents are very much in need of revision.
