    • An additional experiment was carried out on 6a using acetic acid as the solvent. Surprisingly, we observed a total conversion of starting material and 71a% of cyclized product was detected by HPLC-MS [Agilent 1100, Luna C-18, 10 cmaà - a4.6 mm, 3 Im, mobile phase water/0.1a% formic acid,(A)/MeOH/0.1a% formic acid (B) gradient: t0 = 90a% (A) to t = 20 min, 100a% (B)]. Further experiments are in progress to test the reproducibility and applicability of this process as a general method for the cyclization of (bromophenyl) oxoethylpyridinium bromides 6. Improvement of the solubility of phenacylpyridinium salt 6a could play a role in the observed effect.
