  Reaction of 4-hydroxycoumarin with arylglyoxals and ureas

  摘要：

  One-pot condensation of 4-hydroxycoumarin with arylglyoxals and ureas gave 4-aryl-5-(4-hydroxy-2-oxo-2H-chromen-3-yl)-1H-imidazol-2(3H)-ones. The same compounds may be obtained from aroylbis(4-hydroxy-2-oxo-2H-chromen-3-yl)methanes and urea. The reaction of 4-bromobenzaldehyde with 4-hydroxycoumarin in the presence of urea led to the formation of the corresponding Michael adduct without participation of urea.
