This invention related to a series of new phosphonic acid derivatives having anti- hyperphosphatemia activity. (I)
[wherein: A is selected from -(CH2)n-, -CO-, -(CH2)n -CO-(CH2)m-, -(CH2)n -CS-(CH2)m- or branched alkylene group. B ring and C ring are selected from benzene ring, naphthalene ring, azulene ring or, heterocycle or fused heterocycle. D is -(CH2)(n+1)-, -(CH2)-O-(CH2)m-, -(CH2)-S(O)o-(CH2)m-, -CF3 or -(CH2)n-NR10-(CH2)m- (wherein: D ring is connected with the carbon atom composing C ring.). E is selected from oxygen atom or sufur atom. P is phosphine atom. R1 ~ R7 (wherein R1 and R2, R4 and R5 are joined together with neighbored carbon atom to form 5 ~ 7 membered saturated or unsaturated hydrocarbon ring, or 5 ~ 6 membered fused hetrocycle. R1, R2 and R3 are not hydrogen atom if B ring is benzene ring.) may be the same or different and are substituents. R8 and R9 are may be the same or different and are substituents. R10 is alkyl group. n and m are 0-10. o is 0-2.
