Abstract

The reaction of 3‐(3‐aryl‐3‐oxopropenyl)chromen‐4‐ones with 1,2‐phenylenediamine resulted in 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 ^1^H and ^13^C assignments have been performed by a combination of various one‐ and two‐dimensional NMR experiments. Copyright © 2006 John Wiley & Sons, Ltd.
