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

General Synthetic Method for Si-Fluoresceins and Si-Rhodamines
The century-old fluoresceins and rhodamines persist as flexible scaffolds for fluorescent and fluorogenic compounds. Extensive exploration of these xanthene dyes has yielded general structure-activity relationships where the development of new probes is limited only by imagination and organic chemistry. In particular, replacement of the xanthene oxygen with silicon has resulted in new red-shift...
