A series of O,O'-dialkyl-α-phenyl-α-phenylsulfonyloxy-methylphosphonates were synthesized from α-hydroxy-phosphonate and benzene sulfonyl chloride under ultrasound. Effects of different solvents, reaction time, reaction temperature and ultrasound power on the yield were investigated. The optimum reaction conditions were obtained. The method has some distinct advantages such as convenient, short reaction time and high yields. Their structures were clearly established by 1H NMR, IR, MS and elemental analysis, and the fragmentation pathways of them were studied. Preliminary results in bioactivity tests indicated that some title compounds exhibited better activity against A-549.
Key words: α-hydroxyphosphonate; sulfonate; ultrasonic synthesis; antitumor activity
