Highly Efficient Palladium-Catalyzed Boronic Acid Coupling Reactions in Water: Scope and Limitations

, p. 7170 - 7173 (1997)
The "ligandless" palladium acetate-catalyzed Suzuki cross-coupling reaction of ArX with aryl- and vinylboronic acids in water without organic cosolvent in the presence of tetrabutylammonium bromide is reported. Aryl bromides give high yields and considerably accelerate the coupling. A wide variety of functional groups can be tolerated. Aryl iodides, however, give incomplete conversion and aryl triflate coupling shows no improvement over reported conditions.

The invention relates to sulfonamide derivatives, to their use in medicine, to compositions containing them, to processes for their preparation and to intermediates used in such processes. More particularly the invention relates to a new sulfonamide Nav1.7 inhibitors of formula (I), or a pharmaceutically acceptable salt thereof, wherein X, R1, R2, R3a, R3b and R4 are as defined in the description. Nav 1.7 inhibitors are potentially useful in the treatment of a wide range of disorders, particularly pain.
