  • Asymmetric benzoxanthene dyes
    Patent number: 7179906
    Abstract: A class of asymmetric monobenzoxanthene compounds useful as fluorescent dyes are disclosed having the structure wherein Y1 and Y2 are individually hydroxyl, amino, imminium, or oxygen, R1–R8 are hydrogen, fluorine, chlorine, alkyl, alkene, alkyne, sulfonate, amino, amido, nitrile, alkoxy, linking group, and combinations thereof, and R9 is acetylene, alkane, alkene, cyano, substituted phenyl, and combinations thereof. The invention further includes novel intermediate compounds useful for the synthesis of asymmetric benzoxanthene compounds having the general structure where substituents R3–R7 correspond to like-referenced substituents in the structure of described above, and Y2 is hydroxyl or amine. In another aspect, the invention includes methods for synthesizing the above dye compounds and intermediates.
