摘要

Boron trifluoride diethyl etherate catalyzes the Mannich-type reaction of 2-trifluoromethyl-4-bromoaniline and 0,0-dialkylphosphite with 2-fluorobenzoaldehyde under ultrasonic irradiation to synthesize the corresponding product alpha-aminophosphonate. The advantages of the procedure include short reaction period, high yield and simple working up. Their structures were clearly established by IR, H-1 NMR, C-13 NMR and elemental analysis. The bioassay tests showed that the title compounds exhibit moderate antitumor activity in vitro by MTT method. (c) 2005 Elsevier B.V. All rights reserved.
