N-Bromosuccinimide-Mediated Thiocyanation of Cyclohexene-Fused Isoxazoline N-Oxides

An efficient, metal-free, NBS-mediated thiocyanation protocol has been developed for the synthesis of (6-(hydroxyimino)-2-thiocyanatocyclohex-1-en-1-yl)(phenyl)methanone derivatives from cyclohexene-fused isoxazoline N-oxides under mild conditions. This rapid, one-pot transformation is achieved in acetonitrile, and provides access to diverse SCN-containing compounds bearing a wide range of functional groups in good to excellent yields. Moreover, an SCN containing product was further utilized for the synthesis of cyclohexanone ring-fused isothiazole derivatives.

Theoretical Calculation of Thermodynamic and Kinetic Quantities for 1,3 Dipolar Cycloaddition Reactions Between Nitrile Sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) with 7-10 Membered Simple Cycloalkynes

The 1,3-dipolar cycloaddition reactions also known as the Huisgen cycloaddition are one of the most widely used and versatile preparative methods in hetro-cyclic chemistry. In this study, the reactivity and strain energy effect of the simple cycloalkynes with substituted Nitrile sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) will be discussed in light of computational studies using DFT methods (B3LYP/6-31G*). The investigation of the structured properties, theoretical thermodynamic and kinetic data of the reactions in 298 K will be presented. The results show increase in the Delta G* by increasing the ring size and decreasing the strain energy of cycloalkynes. Also, the rate constants and the free energy changes in reactions increase as the size of the ring decreases. The relationships of the deviation of the internal bond angle (DIBA, in degrees), pi-strain (S pi) (in kcal mol(-1)), the bond angle of Csp(3)-C C (theta degrees) and Delta G(#)(kcal mol(-1)) for the series of cycloalkynes I-1 to I-4 have investigated.

HETEROCYCLIC HYDRAZONE DERIVATIVES AS INHIBITORS FOR ALUMINUM CORROSION IN HYDROCHLORIC-ACID SOLUTIONS

Corrosion rate of aluminium in 2N HCl solution in presence and absence of N-(o-hydroxybenzylidene)-2-amino-1,2,4-triazole, N-(o-hydroxybenzylidene)-5-amino-4-methyl isothiazole and N-(o-hydroxybenzylidene)-2-aminopyrazine (10(-3)-5 X 10(-6) Mol L-1) has been studied. Three different techniques, namely, weight loss, hydrogen evolution and thermometric have been used. The inhibition efficiencies of the different methods have been found in good agreement. The inhibition effect depends upon both the concentration and the character of the additives. The temperature effect has been studied, and it indicates that the inhibition process occurs through physical adsorption. The degree of surface coverage (O) of the adsorbed additives has been determined, the results obey the Langmuir adsorption isotherm. The effect of the chemical constitution on the order of corrosion efficiency of the studied compounds has also been explained.

Solvation Structures and Deactivation Pathways of Luminescent Isothiazole-Derived Nucleobases: (tz)A, (tz)G, and I-tz

The photophysical relaxation pathways of (tz)A, (tz)G, and I-tz luminescent nucleobases were investigated with the MS-CASPT2 quantum-chemical method and double-zeta basis sets (cc-pVDZ) in gas and condensed phases (1,4-dioxane and water) with the sequential Monte Carlo/CASPT2 and free energy gradient (FEG) methods. Solvation shell structures, in the ground and excited states, were examined with the pairwise radial distribution function (G(r)) and solute-solvent hydrogen-bond networks. Site-specific hydrogen bonding analysis evidenced relevant changes between both electronic states. The three luminescent nucleobases share a common photophysical pattern, summarized as the lowest-lying 1(pi pi*) bright state that is populated directly after the absorption of radiation and evolves barrierless to the minimum energy structure, from where the excess of energy is released by fluorescence. From the (1)(pi pi*)(min) region, the conical intersection with the ground state ((pi pi*/GS)(CI)) is not accessible due to the presence of high energetic barriers. By combining the present results with those reported earlier by us for the pyrimidine fluorescent nucleobases, we present a comprehensive description of the photophysical properties of this important class of new fluorescent nucleosides.

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.

Cascade Trisulfur Radical Anion (S-3(center dot-)) Addition/Electron Detosylation Process for the Synthesis of 1,2,3-Thiadiazoles and Isothiazoles

Trisulfur radical anion (S-3(center dot-)) mediated reactions with in situ formed azoalkenes and alpha,beta-usaturated N-sulfonylimines for the construction of 1,2,3-thiadiazoles and isothiazoles has been developed. S-3(center dot-) is in situ generated from potassium sulfide in DMF. These two approaches provide a new, safe, and simple way to construct 4-subsituted 1,2,3-thiadiazoles, 5-subsituted 1,2,3-thiadiazoles, and isothiazole in good yields. The reactions include the formation of the new C-S and N-S bonds via S-3(center dot-) addition and electron detosylation under mild conditions.

Molecular Docking and 3D QSAR Studies of Chk2 Inhibitors

Isothiazole-carboxamidines are potent ATP competitive checkpoint kinases (Chk2) inhibitors. Three-dimensional quantitative structure-activity relationship models were developed using comparative molecular field analysis and comparative molecular similarity indices analysis. The study was performed using three different geometrical methods. In geometrical method-1, molecules were fully optimized by PM3 Hamiltonian and aligned using common substructure. This alignment was subsequently used for Ligand-based comparative molecular field analysis and comparative molecular similarity indices analysis. In receptor-guided analyses, the receptor coordinates were obtained from public domine (PDB 2cn8). The molecule-7 was docked into receptor protein using FlexX and two plausible binding modes were identified. These modes were used as templates for geometrical method-2 and 3. These methods were used for 3D QSAR. The geometrical method-3-based comparative molecular field analysis (q (2) = 0.75, r (2) = 0.87 and r (2)(predict) = 0.81) and comparative molecular similarity indices analysis (q (2) = 0.90, r (2) = 0.96 and r (2)(predict) = 0.75) gave better result. The steric, hydrophobic and hydrogen bond donor fields effects significantly contribute to activity. In this way, the receptor-guided study presents a more detailed understanding about chk2 active site interactions. The study indicated some modifications to the active molecule which might be valuable to improve the activity.
