Abstract:
We report the synthesis and use of sydnone-based profluorophores as tools for imaging applications. These new probes display exquisite reactivity towards strain promoted cycloaddition reactions with cycloalkynes allowing fast, efficient and selective labeling in biological media. Styryl-pyridinium sydnone probes were found particularly interesting for click reactions to proceed selectively inside cells.
