Some novel O,O'-diakyl-α-(6-methoxybenzothiazol-2-ylamino)-4-fluorophenylphosphonates (3) have been synthesized through the reaction of Schiff base with dialkyl phosphite. Their struc-tures were clearly established by elemental analysis, IR, 1H NMR, 13C NMR and X-ray diffraction analysis. The crystal of compound 3d belongs to tetragonal with space group I4(1)/a, a=2.1055(3) nm, b=2.1055(3) nm, c=2.0521(5) nm, α=90.00°, β=90.00°, γ=90.00°, V=0.9098(3) nm3, Z=16, Dc=1.321 mg/m3, α=0.250 mm-1, F(000)=3808. There exists an intramolecular hydrogen bond [N(2)—H(2)…O(1)] in the molecule of 3d. Bioassay tests showed that compound 3f could inhibit PC3 cell proliferation at the concentration of 20 g/mL with the inhibition rate 84.3%.
