A concise and one-pot cascade method has been developed to achieve the synthesis of difluoroboron-derivatized curcumins (BF2C). Treatment of 2,4-pentanedione with BF3·OEt2, followed by condensation with aldehydes in the presence of tributyl borate and butylamine at 65 °C in toluene furnished the corresponding symmetric (s-BF2C) and unsymmetric difluoroboron-derivatized curcumins (us-BF2C) in good (60 - 99%) and moderate yields (23 - 42%) within 6 - 12 h, respectively.
