A Divergent and Selective Synthesis of Isomeric Benzoxazoles from a Single N-Cl Imine

A divergent and regioselective synthesis of either 3-substituted benzisoxazoles or 2-substituted benzoxazoles from readily accessible ortho-hydroxyaryl N-H ketimines is described. The reaction proceeds in two distinct pathways through a common N-Cl imine Intermediate: (a) N-O bond formation to form benzisoxazole under anhydrous conditions and (b) NaOCl mediated Beckmann-type rearrangement to form benzoxazole, respectively. The reaction path also depends on the electronic nature of the aromatic ring, with the electron-rich aromatic rings favoring the rearrangement and the electron-deficient rings favoring the N-O bond formation. A Beckmann-type rearrangement mechanism via net [1,2]-aryl migration for the formation of 2-substituted benzoxazole is proposed.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 719-64-2. The above is the message from the blog manager. HPLC of Formula: C13H8ClNO.

Synthesis and binding affinities of a series of 1,2-benzisoxazole-3-carboxamides to dopamine and serotonin receptors

A series of 1,2-benzisoxazole-3-carboxamides derived from tertiary cycloalkylamines was synthesized and evaluated for affinity for serotonergic (5-HT3 and 5-HT4) and dopaminergic (D-2) receptors using radioligand binding assays. The majority of compounds displayed a very weak affinity for the studied neurotransmitter receptors. Only amides containing a conformationally rigid system retained a relative 5-HT3 receptor affinity. The presence of a quinuclidine group affected receptor interaction more favorably than the tropane framework.

Zonisamide: Review of Recent Clinical Evidence for Treatment of Epilepsy

Zonisamide is an orally administered antiepileptic drug that was first approved for clinical use in Japan in 1989. Since then, it has been licensed in Korea for a broad spectrum of epilepsies in adults and children, and in the USA for adjunctive therapy of adults with partial seizures, and in Europe for monotherapy of adults with newly diagnosed partial seizures and adjunctive therapy of adults and adolescents and children aged 6years with partial seizures with or without secondary generalization. Zonisamide is a benzisoxazole derivative with a unique chemical structure, predictable dose-dependent pharmacokinetics, and multiple complementary mechanisms of action. Treatment with zonisamide is well tolerated and is not known to be associated with clinically significant drug-drug interactions, including with oral contraceptives or other antiepileptic drugs. There have been >2million patient-years of experience with zonisamide for treatment of epilepsy, and this drug has International League Against Epilepsy level A evidence for efficacy/effectiveness as initial monotherapy for adults with partial-onset seizures. This review presents the evidence for zonisamide across the spectrum of epilepsy, with emphasis on real-world clinical practice and special populations of patients (children, elderly patients, and women of childbearing age) who are likely to be treated in daily clinical practice.

Copper-catalyzed synthesis of benzo[d]isothiazol-3(2H)-ones and N-acyl-benzothiazetidine by intramolecular dehydrogenative cyclization is described. In this reaction, a new nitrogen sulfur (N-S) bond is formed by N-H/S-H coupling. The present reaction has high functional group tolerance and gives products in gram scale. This method promotes double cyclization, allowing for synthesis of a drug intermediate.

Zonisamide suppresses the tonic phase but not the clonic phase of generalized seizures in developing rats

Zonisamide is increasingly used in pediatric neurology but there are no experimental data for immature animals. Zonisamide (12.5-100 mg/kg i.p.) was tested against pentetrazol-induced seizures in 7-, 12-, 18-, 25- and 90-day-old rats. Minimal clonic seizures were not suppressed by zonisamide. Selective suppression of tonic phase of generalized tonic-clonic seizures was demonstrated in all age groups. This effect indicates possible action of zonisamide against generalized tonic-clonic seizures during brain maturation. (C) 2010 Published by Elsevier B.V.

In the title compound, C18H11ClN4OS, the benzisoxazole and imidazothiadiazole rings are inclined at an angle of 23.81 (7)degrees with respect to each other. The imidazothiadiazole and chlorophenyl rings make a dihedral angle of 27.34 (3)degrees. In the crystal, intermolecular C-H center dot center dot center dot N interactions generate a chain along the c axis and C-H center dot center dot center dot O interactions form centrosymmetric dimers resulting in an R-2(2)(26) graph-set motif. Moreover, the C-H center dot center dot center dot N and S center dot center dot center dot N [3.206 (4) angstrom] interactions links the molecules into R(7) ring motifs.

Effects of medium on decarboxylation kinetics: 3-Carboxybenzisoxazoles and their potential use as environmental probes in biochemistry

The decarboxylation rate of the tetramethylguanidinium salt of 3-carboxy-6-nitrobenzisoxazole in 24 pure solvents and 36 dimethyl sulfoxide binary mixtures with diglyme, acetonitrile, benzene, dichloromethane, chloroform, and methanol was analyzed in the light of the SPP, SA, and SB pure solvent scales. The results allow one to rationalize the high sensitivity of this kinetics to the reaction medium and to assess the potential use of this compound as a probe in biochemical environments. The natural environment for comparison of this kinetics was found to be the gas phase rather than the aqueous medium. In the latter, the process is much faster owing to such high polarity, which, however, is strongly diminished by the high acidity of the medium. Based on our calculations, the rate constant for the decarboxylation kinetics in the gas phase; must be in the region of 2 x 10(-10) s(-1) (i.e., 3 orders of magnitude smaller than in water).
