EDA Complexes of N-halosaccharins with N- and O-donor ligands

A series of EDA complexes of N-iodosaccharin (NISac) and N-bromosaccharin (NBSac) with nitrogen and oxygen electron-pair donors, NISac center dot H2O, NISac center dot THF, NISac center dot Py, NISac(2)center dot Pyz and NBSac(2)center dot Pyz, was prepared and examined by X-ray diffraction and NMR. The complexes are relatively stable, crystalline compounds with the ligand bound to the halogen atom in a nearly linear arrangement N-halogen-ligand. The halogen-ligand distances are inversely proportional to the donor ability of the ligand. The interactions between ligand and halogen are stronger for iodine than bromine. The X-ray structure analysis has shown that for some compounds the N-X bond in the halosaccharin moiety is not coplanar with the isothiazole ring, and the quantum-chemical calculations demonstrate a high flexibility of the corresponding angle. Complexes were modelled also by DFT calculations using B3LYP and MPW1K functionals. A better fit of the computed geometry was obtained by the geometry optimization in a polar solvent continuum than in vacuum.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 114772-54-2, you can contact me at any time and look forward to more communication. SDS of cas: 114772-54-2.

Design, synthesis and fungicidal activity of isothiazole-thiazole derivatives

3,4-Dichloroisothiazoles can induce systemic acquired resistance (SAR) to enhance plant resistance against a subsequent pathogen attack, and oxathiapiprolin exhibits excellent anti-fungal activity against oomycetes targeting at the oxysterol-binding protein. To discover novel chemicals with systemic acquired resistance and fungicidal activity, 21 novel isothiazole-thiazole derivatives were designed, synthesized and characterized according to the active compound derivatization method. Compound 6u, with EC50 values of 0.046 mg L-1 and 0.20 mg L-1 against Pseudoperonospora cubensis (Berk. et Curt.) Rostov and Phytophthora infestans in vivo, might act at the same target as oxysterol binding protein (PcORP1) of oxathiapiprolin; this result was validated by cross-resistance and molecular docking studies. The expression of the systemic acquired resistance gene pr1 was significantly up-regulated after treating with compound 6u for 24 h (43-fold) and 48 h (122-fold). These results can help the development of isothiazole-thiazole-based novel fungicides.

THE PREPARATION OF 1,2,3,5-DITHIADIAZOLIUM CHLORIDES FROM THE REACTION OF NITRILE SULFIDES WITH THIAZYL CHLORIDE

Adamantyl-1,3,4-oxathiazol-2-one has been prepared for the first time and from it l-adamantyl nitrile sulphide has been generated. Characterisation data are presented, including the X-Ray crystal structure of the oxathiazolone. (Crystal data for C12H15NO2S: monoclinic, space group P2(1)/c, a = 11.334(2) Angstrom, b = 7.344(1) Angstrom, c = 14.373(2) Angstrom, beta = 107.74(1)degrees, V = 1139.5(3) Angstrom(3), Z = 4, R = 0.042). The planar heterocyclic ring is similar to structures observed in the gas phase for other oxathiazolone derivatives. The nitrile sulphide was reacted with dimethyl-acetylene dicarboxylate in situ to give an isothiazole derivative. The X-Ray crystal structure of 3-adamantyl-4,5-bis(methoxycarbonyl)-isothiazole has been obtained. (Crystal data for C17H21NO4S: monoclinic, space group P2(1)/n, a = 7.305(4) Angstrom, b = 7.339(4) Angstrom, c = 31.552(4) Angstrom, beta = 92.75(3)degrees, V = 1690(1) Angstrom(3), Z = 4, R = 0.079). A general cycloaddition reaction was discovered between the nitrile sulphides and thiazyl chloride to give 1,2,3,5-dithiadiazolium chlorides. The structure of the new 4-adamantyl-1,2,3,5-dithiadiazolium chloride was confirmed by reduction to the 4-adamantyl-1,2,3,5-dithiadiazolyl for which the X-Ray crystal structure has been determined.

Differences in kinetics of structurally related competitive GABA(A) receptor antagonists

Previously, 4-alkyl and 4-aryl substituted analogues of the low-efficacy partial GABA(A) receptor agonist 5-(4-piperidyl)-3-isothiazole (4-PIOL) have been identified as competitive GABAA receptor antagonists. These structurally related competitive antagonists show marked differences in their kinetic properties. The kinetics of 20 4-alkyl and 4-aryl substituted analogues of 4-PIOL, two 4-arylalkyl substituted 3-isothiazolol analogues and the classical GABAA receptor antagonist SR95531 was studied in cultured cerebral cortical neurons using whole-cell patch-clamp techniques. The kinetics of the antagonists was studied indirectly by measuring the changes in the response of the full GABAA receptor agonist isoguvacine (IGU) induced by concurrent application of an antagonist. When added, the majority of the antagonists did not affect the rate of deactivation of the IGU-induced responses. When removed, however, the majority of the antagonists slowed the reactivation phase of IGU implying that the dissociation of the antagonist from the GABAA receptor is the rate-limiting step. Surprisingly, the functional off-rates of the antagonists seemed to correlate better with the lipophilicity of the compounds than with the affinity and potency. This suggests that the dissociation of the tested antagonists from the GABAA receptor is restricted by lipophilic interactions, perhaps with the aromatic amino acids surrounding the GABA binding site.

Enolates of 2-Isothiocyanatocarboxylic Esters: Synthesis of Thiazolo[5,4-d]-thiazole Derivatives and 2-Thioxo-1,3-thiazolidine-4-carboxylates

An oxidative dimerization of titanium(IV) enolates derived from menthyl esters of 2-isothiocarboxylic acids leads to radical coupling followed by cyclization. This cascade reaction gives thiazolo[5,4-d]thiazole derivatives as pure enantiomers. Under similar conditions, 2-methylbutyl esters of 2-isothiocyanatocarboxylic acids undergo intermolecular oxidative dimerization to give mixtures of thiazolo[5,4-d]thiazoles and 2,3-diisothiocyanatosuccinates. Application of the soft enolization technique to dimethyl alpha,alpha’-diisothiocyanatodicarboxylic esters gives novel cyclic 1,2-diisothiocyanato-1,2-dicarboxylates. Sodium enolates of 2-isothiocyanatocarboxylates, on the other hand, form 5-imino-2-thioxo-1,3-thiazolidine-4-carboxylic esters by nonoxidative dimerization. The mechanisms of the two reaction pathways are discussed.
