the unexpected formation of 10a‐aryl‐1,2,10,10a‐tetrahydrobenzo‐[4,5]‐imidazo[1,2‐a]pyridin‐3‐yl(2‐hydroxyphenyl)‐1‐methanones. Their structure elucidation and complete 1H and 13C assignments have been performed by a combination of various one‐ and two‐dimensional NMR experiments. Copyright © 2006 John Wiley & Sons, Ltd.
