  Synthesis of Rhodamines from Fluoresceins Using Pd-Catalyzed C–N Cross-Coupling

  摘要：

  A unified, convenient, and efficient strategy for the preparation of rhodamines and N,N'-diacylated rhodamines has been developed. Fluorescein ditriflates were found to undergo palladium-catalyzed C-N cross-coupling with amines, amides, carbamates, and other nitrogen nucleophiles to provide direct access to known and novel rhodamine derivatives, including fluorescent dyes, quenchers, and latent fluorophores.
