REACTIONS OF CHELATED BETA-FUNCTIONALIZED AMINO-ACIDS WITH THIONYL CHLORIDE

A variety of bis(ethane-1,2-diamine)cobalt(III) complexes containing chelated beta-functionalized amino acids have been treated with SOCl2 in dimethylformamide. These compounds undergo beta-elimination reactions to give chelated enamines followed by either rearrangement to the related imine complexes or further reactions with SOCl2 to give chelated isothiazole-3-carboxylato complexes. Mechanisms are proposed for the reactions.

Rhodium-Catalyzed Annulative Coupling of Isothiazoles with Alkynes through N-S Bond Cleavage

A Rh(III)-catalyzed annulative coupling of 3,5-diarylisothiazoles and alkynes is reported. The N-S bond in the isothiazole ring acts as an internal oxidant to regenerate the Rh(III) species in combination with an external Cu(II) oxidant, and the corresponding 1:2 coupling products are obtained. The remarkable difference in the reaction outcome between isothiazoles and the relevant isoxazoles has been investigated by DFT calculations, revealing that the relative stability of the enolate intermediates dictates the product selectivity.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 22884-95-3. COA of Formula: C9H9N.

Synthesis and pharmacology of glutamate receptor ligands: new isothiazole analogues of ibotenic acid

The naturally occurring heterocyclic amino acid ibotenic acid (Ibo) and the synthetic analogue thioibotenic acid (Thio-Ibo) possess interesting but dissimilar pharmacological activity at ionotropic and metabotropic glutamate receptors (iGluRs and mGluRs). Therefore, a series of Thio-Ibo analogues was synthesized. The synthesis included introduction of substituents by Suzuki and Grignard reactions on 4-halogenated 3-benzyloxyisothiazolols, reduction of the obtained alcohols, followed by introduction of the amino acid moiety by use of 2-(N-tert-butoxycarbonylimino) malonic acid diethyl ester. The obtained Thio-Ibo analogues ( 1, 2a- g) were characterized in functional assays on recombinant mGluRs and in receptor binding assays on native iGluRs. At mGluRs, the activity at Group II was retained for compounds with small substituents (2a – 2d), whereas the Group I and Group III receptor activities for all new compounds were lost. Detection of NMDA receptor affinity prompted further characterization, and two-electrode voltage-clamp recordings at recombinant NMDA receptor subtypes NR1/NR2A-D expressed in Xenopus oocytes were carried out for compounds with small substituents ( chloro, bromo, methyl or ethyl, compounds 2a – d). This series of Thio-Ibo analogues defines a structural threshold for NMDA receptor activation and reveals that the individual subtypes have different steric requirements for receptor activation. The compounds 2a and 2c are the first examples of agonists discriminating individual NMDA subtypes.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 398489-26-4, in my other articles.

The design, synthesis, and biological evaluation of potent inhibitors of the TrkA kinase is presented. A homology model is created to aid in the enhancement of potency and selectivity of isothiazole inhibitors found during a high-throughput screen. Three different syntheses are utilized to make diverse analogs within this series. Aminoheterocycles are found to be good urea surrogates, whereas bicyclic substituents on the C3 thio group were found to be extremely potent TrkA inhibitors in kinase and cell assays.

The electronic states of isothiazole studied by VUV absorption spectroscopy and ab initio configuration interaction methods

The isothiazole VUV absorption spectrum over the range 5-12 eV shows (broad) intense bands centred near 5.17, 6.11, 7.37, 7.75, 9.18 and 10.43 eV. The lowest Rydberg states relating to the first ionisation energy are difficult to identify, but higher members are particularly numerous on the region from 8.4 to 9.6 eV. Electronic excitation energies for valence (singlet and triplet) and Rydberg-type states have been computed using ab initio multi-reference multi-root CI methods. These studies used a triple zeta + double polarisation basis set, augmented by diffuse (Rydberg) orbitals. The theoretical study shows the nature of the more intense Rydberg state types, and positions of the main valence and Rydberg bands. By study of the excitation energies to specific upper states, the vertical ionisation energies (IE) are confirmed as pi(-1)(4) < pi(-1)(3) < sigma(-1)(18)(LPN) < sigma(-1)(17)(LPs). Structures for the pi- and sigma-cations, and the (neutral) pi pi*-triplet states have been obtained. Calculated energies for low-lying Rydberg states are close to those observed, and there is generally a good correlation between the theoretical intensities and the experimental envelope. The ground state atomic and molecular properties are in good agreement with experiment. (C) 2007 Elsevier B.V. All rights reserved. Interested yet?

Further reactions of furans with trithiazyl trichloride; mechanistic considerations

The reaction of 2,5-diarylfurans with trithiazyl trichloride 1 to give 5-aroyl-3-arylisothiazoles in a useful one-step synthesis of isothiazoles has been extended to both weakly and strongly polarised unsymmetrical 2,5-diarylfurans, These react in an entirely analogous manner; the more electron releasing aryl group becomes incorporated into the 5-aroyl group of the isothiazole as the exclusive (strong polarisation) or the major (weak polarisation) product, However, with 3-bromo-2-(4-methoxyphenyl)-5-(4-nitrophenyl)-furan 7, where the more reactive furan beta-position is now substituted, this regiospecificity is reversed (to give isothiazole 8), When one of the alpha-aryl groups in the furan is replaced by methyl the same regiospecific isothiazole formation is now accompanied by some ring and side chain chlorination (15–>16 + 17 + 18), All of these results can be explained by mechanisms (Schemes 2 and 5) which involve initial electrophilic attack of the furan to give a beta-thiazyl derivative, This highly reactive (nitrenoid) substituent then induces a novel opening of the furan ring 21 to give a highly delocalised intermediate 22 which recyclises to the isothiazole.
