Synthesis of 2,2'-arylmethylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one) derivatives catalyzed by urea via the condensation of aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione was carried out in 80-98% yields at 50 degrees C in aqueous media under ultrasound. This method provides several advantages such as environment friendliness, high yields and simple work-up procedure. (C) 2011 Elsevier B.V. All rights reserved.
