The formation of biofilms by clinical pathogens typically leads to chronic and recurring antibiotic-resistant infections. High cellular levels of cyclic diguanylate (c-di-GMP), a ubiquitous secondary messenger of bacteria, have been proven to be associate

A series of π-conjugated vinyl N-methylated quinolinium salts (3) and their precursor's N-alkylated quinolinium salts (2) were prepared and characterized by NMR, IR, UV-Vis and MS spectroscopy. It was confirmed that the hydroxyl and amino derivatives of vinyl N-methylated quinolinium salts lead to spiro type compounds (4). The syntheses of N-alkylated quinolinium salts were successful, and even multigram scale was achievable. The structures of 1,2-dimethylquinolinium iodide (2a) and 1-ethyl-2-methylquinolinium iodide (2b) were determined by single crystal X-ray diffraction method. NMR spectra showed readily diagnostic H-1 and C-13 signals from methyl and N-alkyl groups for both 2 and 3. The geometries of the studied compounds were optimized in singlet states using the density functional theory (DFT) method with B3LYP functional. In general, the predicted bond lengths and angles are in a good agreement with the values based on the X-ray crystal structure data.

Methylpyridinium and methylquinolinium salts were condensed under solvent-free conditions with aromatic aldehydes in the presence of 1,8-diazabicyclo[5.4.]undec-7-ene (DBU) as catalyst, by grinding at room temperature. The products are dyes or useful intermediates. The DBU can be easily recycled and reused. Taylor & Francis Group, LLC.
