Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 123-76-2, Name is 4-Oxopentanoic acid, SMILES is C(C(C)=O)CC(O)=O, in an article , author is Forconi, Marcello, once mentioned of 123-76-2, SDS of cas: 123-76-2.

Medium Effects in Biologically Related Catalysis

Enzymes catalyze chemical reaction in aqueous media, but their active sites significantly differ in properties from water. In this chapter, the work on selected chemical reactions with important biological roles is reviewed to assess our current understanding of the effect of the environment that surrounds the reactive species. In particular, simple medium effects such as the ones provided by organic solvents, ionic liquids, and simple micelles are focused on. The findings that led to the computational design of enzymes that catalyze the Kemp elimination, a prototypical proton transfer reaction that has fascinated researchers for more than a century, are discussed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 123-76-2, you can contact me at any time and look forward to more communication. SDS of cas: 123-76-2.

One-pot and catalyst-free synthesis of pyrroloquinolinediones and quinolinedicarboxylates

A method for the catalyst-free synthesis of pyrroloquinolinediones and quinolinedicarboxylates is developed through a one-pot synthesis involving denitrogenation of azide, benzisoxazole formation, aza-Diels-Alder cycloaddition, and dehydrative aromatization. Only stoichiometric amounts of N-2 and H2O are produced as by-products. A comprehensive green chemistry metrics analysis indicated that this method is much more efficient and greener than two reported methods for the synthesis of pyrroloquinolinediones.

ZONISAMIDE REDUCES HYPOXIC-ISCHEMIC BRAIN-DAMAGE IN NEONATAL RATS IRRESPECTIVE OF ITS ANTICONVULSIVE EFFECT

The neuroprotective effect of a novel anticonvulsant, zonisamide, was investigated in neonatal rats with hypoxic-ischemic brain damage. Rats underwent left carotid ligation followed by hypoxic exposure (8% 0(2)) for 2.5 h. When zonisamide (75 mg/kg) was administered i.p. 1 h before hypoxia, it reduced the cortical infarction volume to 6 +/- 5% (mean +/- S.E.M.) from 68 +/- 7% in vehicle-treated controls and the striatal volume to 8 +/- 4% from 78 +/- 7%. Zonisamide also reduced neuronal necrosis in 5 hippocampal regions (the dentate gyrus, CA4, CA3, CA1, and the subiculum). The plasma zonisamide concentration before and after hypoxia was 47.9 +/- 2.0 mu g/ml and 42.3 +/- 3.9 mu g/ml, respectively. Epidural electrodes were implanted in 6 pups one day before hypoxia-ischemia. Electroencephalograms were recorded during hypoxia-ischemia in rats given zonisamide or vehicle before the insult. The intensity of seizure activities was similar in the zonisamide-treated pups and the vehicle-treated controls. These findings demonstrate that zonisamide reduces neonatal hypoxic-ischemic brain damage and that this protective effect does not depend on its anticonvulsant action.

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.

REARRANGEMENTS IN THE MOLECULAR-IONS OF SOME ORTHO-SUBSTITUTED SCHIFF-BASES

Under electron ionization conditions, the ortho-substituted Schiff bases N-benzylidene-o-toluidine (1a), N-(o-methylbenzylidene)aniline (1b), N-salicylideneaniline (1c) and N-(o-methoxybenzylidene)aniline (1d) give fragment ions which have been shown by collision-activated mass-analysed ion kinetic energy spectra to have the structure of the protonated molecular ions of indole (2), benzofuran (3), and 1,2-benzisoxazole (4). The molecular ion of N-(o-methylbenzylidene)-o-toluidine (1f) gives as fragment ions not only the protonated molecular ion (2) of indole and the tropylium ion but also the molecular ion of anthracene. Attempts to find supporting evidence for a mechanism for this rearrangement by deuterium labelling of a methyl group in (1b), such as (1g), have been unsuccessful.

A series of substituted 7,8-dihydrofuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acids 9 and 7,8-dihydrofuro[2,3-g]benzoxazole-7-carboxylic acids 12 were synthesized and evaluated for uricosuric and diuretic activities in rats. Many of the benzisoxazole derivatives 9 showed uricosuric and only weak diuretic activities, whereas the benzoxazoles 12 exhibited potent diuretic activities with little affecting urate excretion. Among these compounds, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (9b, AA-193) was found to be a potent uricosuric agent without diuretic activity and was selected for further development.

A mild procedure for the production of secondary amines from oximes and benzisoxazoles

-2-Hydroxybenzaldoximes are reduced under mild conditions of ammonium formate/Pd-C in methanol to give secondary amines. Benzisoxazoles react under the same mild conditions to give the same products. A possible mechanism is suggested, involving the intermediacy of the benzisoxazole in the oxime conversion. (C) 2003 Elsevier Ltd. All rights reserved.

Dependence of isotope effects on conformation in decarboxylation of 3-carboxybenzisoxazoles

Conformational analysis of 3-carboxybenzisoxazole and its 4-hydroxy-substituted derivative was performed by a semiempirical molecular dynamics approach. The most stable conformers of the reactants and transition states from these simulations were used in calculations of the kinetic isotope effects of carbon, nitrogen, oxygen and deuterium. It was shown that the conformation of either reactant or transition state can significantly affect the magnitude of an isotope effect, especially for atoms involved in hydrogen bonding.
