N-(3-Hydroxy-2-pyridyl)benzamides 3(a-J) were synthesized under weak basic solution by reacting of 2-amino-3-pyridinol and an appropriate carboxylic acid chloride, obtained by reaction of carboxylic acids with thionyl chloride. The microbiological activity of these compounds was tested in vitro against Escherichia Coil (PTCC 1338), Pseudomonas aeruginosa (PTCC 1074), Entrococcus faecalis (PTCC 1237) and Staphylococcus aureus (PTCC 1119) bacteria. Compounds 3a, 3e and 3f were the active benzamide derivatives against the Ef and Sa bacteria with a MIC value of 128 μg/ml. Compound 3g was the active entry against Ec and Pa bacteria with a MIC value of 128 μg/.

We report the directed assembly of single-walled carbon nanotubes (SWCNTs) at lithographically defined positions on gate oxide surfaces, allowing for the high yield (~90%) and parallel fabrication of SWCNT device arrays. SWCNTs were first chemically funct

A general and efficient iodine-promoted chlorination of amides and esters with phosphorus trichloride is described. For the first time. Various inactivated amides including secondary and tertiary amides were directly converted to the corresponding acid chlorides in one-step. The substrate scope of methyl esters including aromatic and aliphatic esters was also explored under this system. This method is simple, scalable and wide in scope, which provides an approach to preparation of these acid chlorides.

SBA-15 nanoporous silica was synthesized by hydrothermal method using P123 surfactant and tetraethoxyortosilicate in acidic condition and then functionalized by 3-chloropropyltrimethoxysilane. Next, by immobilization of chiral amino acid (S)-2-amino-3-methyl butanoic acid (l-valine) and chiral amino alcohol (S)-2-amino-3-methylbutane-1-ol (l-valinol), preparedviathe reduction ofl-valine by NaBH4/I2in THF, on functionalized-SBA-15, chiral heterogeneous ligands AL*-i-Pr-SBA-15 and AA*-i-Pr-SBA-15 were prepared and characterized by FT-IR, XRD, TGA, EDX, SEM, BET-BJH techniques. The asymmetric allylic oxidation of alkenes was done using copper-complexes of these ligands and the as-synthesized peresters. The reactions were optimized by varying various parameters such as temperature, solvent, amount of chiral heterogeneous ligand, as well as the type and amount of copper salt. Under optimized conditions, 6 mg of AL*-i-Pr-SBA-15 and 3.2 mol% of Cu(CH3CN)4PF6in acetonitrile at 50 °C, the chiral allylic ester was obtained with 80% yield and 39% enantiomeric excess in 24 h. The recyclability of the chiral heterogeneous catalysts was also evaluated without significant reduction in the reaction results up to three runs.
