Synthesis, Crystal Structure and Biological Activity of 2-(3,4-Dichloroisothiazol-5-yl)-4-(trifluoromethyl)-4,5-dihydrothiazol-4-yl-3-methylbenzoate

The title compound diethyl 2-(3,4-dichloroisothiazol-5-yl)-4-(trifluoromethyl)-4,5dihydrothiazol-4-yl-3-methylbenzoate (C15H9C12F3N2O2S2, M-r = 441.26) was prepared from methyl 3,4-dichloroisothiazole-5-carboxylate as the starting material by four steps of reaction. Its structure was characterized by IR, H-1-NMR, C-13-NMR, EA and single-crystal X-ray diffraction. The crystal of the title compound belongs to the monoclinic system, space group P2(1)/c with a = 8.8437(18), b = 16.128(3), c = 12.305(3) angstrom, beta = 91.68(3)degrees, V= 1754.4(6) angstrom(3), Z= 4, D-c = 1.671 g/cm(3) mu(MoKa) = 0.71073 mm(-1), F(000) = 888, R = 0.0384 and wR = 0.0778. Weak pi-pi interactions occur between the isothiazole rings and phenyl rings of adjacent molecules to form a one-dimensional chain and stabilize the crystal structure. Bioassay indicates that the title compound has good activity against the fungi and TMV tested.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 530-48-3. Name: Ethene-1,1-diyldibenzene.

Isothiazolo[5,4-d]isoxazole S,S-dioxides and pyrazolo [3,4-d]-isothiazole S,S-dioxides through cycloaddition reaction on 3-benzylaminoisothiazole S,S-dioxides

By reacting 4,5-unsubstituted isothiazole dioxides with diazoalkanes and nitrile oxides bicyclic pyrazolo[3,4-d]isothiazole and isothiazolo[5,4-d]isoxazole SS-dioxides were obtained in good yield through a regioselective cycloaddition reaction. Through cycloaddition reaction of 3-benzylamino-4-bromo-isothiazole SS-dioxide labile cycloadducts were formed that underwent in situ dehydrobromination affording the corresponding aromatized compounds.

CONDENSATION OF MUSCIMOL OR THIOMUSCIMOL WITH AMINOPYRIDAZINES YIELDS GABA-A ANTAGONISTS

Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3-aminopyridazines with (chloromethyl) isoxazole or (chloromethyl)isothiazole derivatives. These muscimol and thiomuscimol derivatives show potent binding properties for GABA-A receptors (they displace [H-3]GABA and [H-3]gabazine) and provoke convulsions after iv injections. They fit well with the model pharmacophore proposed by our group for the GABA-A antagonists and show similar structure-activity profiles to that of the pyridazinyl-GABAs.

NEGATIVE-ION FRAGMENTATIONS OF DEPROTONATED HETEROCYCLES – THE ISOTHIAZOLE, THIAZOLE, ISOXAZOLE, AND OXAZOLE RING-SYSTEMS

The major collision-induced dissociations of deprotonated isothiazole occur from the 5-anion, while deprotonated thiazole fragments almost equally through the 2- and 5-anions. Both 5-anions fragment by a simple retro cleavage yielding HC2S- and HCN. The 5-anion of isothiazole and the 2-anion of thiazole also rearrange to the common intermediate -SCH = CHCN which decomposes by losses of H-2, HCN and H2S, There is no evidence for direct interconversion of isothiazole and thiazole anions. The spectra of deprotonated methylisothiazoles and methylthiazoles are complex, but the major fragmentations are of ring deprotonated ions and are generally analogous to the parent systems. The fragmentation behaviour of deprotonated isoxazole and oxazole is analogous to that of the isothiazole and thiazole systems.

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 58446-52-9, in my other articles.

The concerted and stepwise chemisorption mechanisms of isothiazole and thiazole on Si(100)-2 x 1 surface

The surface reaction pathways of isothiazole and thiazole on Si(100)-2 x 1 surface were theoretically investigated using multireference wavefunctions. In the case of isothiazole, the Si-N dative adduct turned out to be the major surface product. In contrast, a direct reaction competition between a concerted [4 + 2](CC) cycloaddition and Si-N dative adduct was found in the adsorption of thiazole. Therefore, it is concluded that the particular geometric arrangements of heteroatoms exhibit distinctly different initial surface reaction mechanisms.

Ibotenic acid and thioibotenic acid: a remarkable difference in activity at group III metabotropic glutamate receptors

In this study, we have determined and compared the pharmacological profiles of ibotenic acid and its isothiazole analogue thioibotenic acid at native rat ionotropic glutamate (iGlu) receptors and at recombinant rat metabotropic glutamate (mGlu) receptors expressed in mammalian cell lines. Thioibotenic acid has a distinct pharmacological profile at group III mGlu receptors compared with the closely structurally related ibotenic acid; the former is a potent (low mum) agonist, whereas the latter is inactive. By comparing the conformational energy profiles of ibotenic and thioibotenic acid with the conformations preferred by the ligands upon docking to mGlu(1) and models of the other mGlu subtypes, we propose that unlike other subtypes, group III mGlu receptor binding sites require a ligand conformation at an energy level which is prohibitively expensive for ibotenic acid, but not for thioibotenic acid. These studies demonstrate how subtle differences in chemical structures can result in profound differences in pharmacological activity. (C) 2004 Elsevier B.V. All rights reserved.

Oxazol-2-ylidenes. A new class of stable carbenes?

The investigation of the stability of several imidazol-2-ylidene analogue cyclic carbenes by an isodesmic reaction has revealed that the hitherto unknown oxazol-2-ylidene exhibits only slightly smaller stability than imidazol-2-ylidene, outperforming some of the already synthesized carbenes. Selenazol-2-ylidene also shows significant stability. The contribution of aromaticity to the stabilization has been analysed for the different five-membered ring carbenes, and was found to be relatively small for the oxygen containing systems. Investigation of possible reactivity/decomposition pathways reveals that properly substituted oxazol-2-ylidene is stable against dimerization. The thermodynamically feasible cycloreversion reaction yielding isocyanate and acetylene is prevented by a significant barrier, and furthermore with proper substitution (ring annellation) the ring can be stabilized thermodynamically as well. While in the presence of water a hydrolytic ring opening occurs; this reaction can be hindered if the water content of the reaction mixture is reduced to a few equivalents. This hydrolytic behaviour as well as the electrophilicity and nucleophilicity indices of several known nucleophilic carbenes were compared, revealing that oxazol-2-ylidene exhibits a reduced nucleophilicity with respect to imidazol-2-ylidene, while its electrophilicity is only slightly increased. This unique combination might result in unexpected (organo) catalytic activities, further expanding the colourful applications of NHCs.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 35271-74-0. The above is the message from the blog manager. COA of Formula: C11H11ClO4.

Conversion of pyrroles into bis-1,2,5-thiadiazoles: a new route to biheterocycles

Trithiazyl trichloride 1 converts 1-aryl-2,5-diphenylpyrroles 2c into isothiazole imines 3c, but 1-alkyl-2,5-diphenylpyrroles (e.g. 4) react very differently to give the bis-1,2,5-thiadiazole 5 in which two N-S-N units have been fused onto the pyrrole and the alkyl-N unit has been excised, in a new dissection of the pyrrole ring, thus providing a novel route to an aromatic biheterocycle.
