A convenient and efficient method was developed for the synthesis of 2,2′-(arylmethylene)bis(3-hydrox- ycyclohex-2-enone) derivatives via the oleylamine-catalyzed tandem Knoevenagel/Michael addition reactions of aromatic aldehydes and cyclohexane-1,3-diones. This transformation proceeded without any metal catalyst in non-toxic solvent at room temperature with high isolated yields. A plausible mechanism for this process was pro-posed.
