New profluorescent mono- and di-isoindoline nitroxides (5, 11, 16 and 19) containing 9,10-diphenylanthracene and 9,10-bis(phenylethynyl)anthracene structural cores were synthesised by palladium-catalysed Suzuki and Sonogashira couplings. These nitroxide-fluorophore probes possess strongly suppressed fluorescence, even in the presence of only one nitroxide radical. Upon reduction, or reaction with other

The methoxyamine group represents an ideal protecting group for the nitroxide moiety. It can be easily and selectively introduced in high yield (typically >90%) to a range of functionalised nitroxidesusing FeSO4.7H2O and H2O2 in DMSO. Its removal is readily achieved under mild conditions in high yield (70-90%) using mCPBA in a Cope-type elimination process.
