Popis: | Reported herein is a regioselective difluoromethane sulfonylation or triflylation of resorufin derivatives, which allows easy access to 2-difluoromethane sulfonylated or triflylated resorufin derivatives in good yields. The installation of a difluoromethane sulfonyl group significantly increases the solubility of the chromophore and expands its Stokes shift. A difluoromethane sulfonylated resorufin-based fluorogenic probe proved to be able to image enzyme activity in live cells with a stronger fluorescence signal compared with its resorufin counterpart. |
