Identification, library synthesis and anti-vibriosis activity of 2-benzyl-4-chlorophenol from cultures of the marine bacterium Shewanella halifaxensis

Summer Gut Syndrome (SGS) is caused by various Vibrio bacterial species and can have negative effects on aquaculture farms worldwide. In New Zealand, SGS is caused by Vibrio harveyii infecting King Salmon (Oncorhynchus tshawytscha). To find leads for the prevention of SGS, we screened the inhibitory effects of 16 strains of Shewanella upon V. harveyii growth in competitive solid phase cultures. The detailed investigation of Shewanella halifaxensis IRL548 revealed 2-benzyl-4-chlorophenol (1), a known, commercially available antibacterial agent, as the major bioactive component. Synthesis of a small library of congeners to confirm the natural product identity and to provide a structure-activity relationship for the observed activity was also completed. Compound 1 exhibits moderate activity against two pathogenic microorganisms.

Chemoselectivity in the microwave-assisted solvent-free solid-liquid phase benzylation of phenols: O- versus C-alkylation

The outcome of the solvent-free benzylation of phenol and 4-substituted phenols (such as 4-cresol and 4-chlorophenol) under MW irradiation was found to depend on the absence or presence of the base (K2CO3) and catalyst (triethylbenzy

Zirconia-modified superacid UDCaT-5: An efficient and versatile catalyst for alkylation reactions under solvent-free conditions

UDCaT-5, a modified version of zirconia, efficiently catalyzes alkylation of phenols with alcohols under environmentally safe, heterogeneous reaction conditions with high selectivity and in excellent yields. The high content present in UDCaT-5 with preservation of tetragonal phase of zirconia was responsible for the superactivity. Several phenolic compounds carrying either electron-sulfer releasing or electron-withdrawing substituents in the ortho, meta, and para positions afforded high yields of the products.

Uncatalyzed Friedel-Crafts alkylation of aromatic compounds through reactive benzyl cations generated from N-sulfamoylcarbamates

(Matrix presented) A new method for the generation of highly reactive benzyl cations by thermal decomposition of aryl-benzyl-sulfamoylcarbamates, obtained in a one-pot reaction from chlorosulfonyl isocyanate, is described. The generated cations alkylate aromatic compounds efficiently in the absence of catalysts.
