Straightforward Route! [RuCl2(p‐cymene)]2 promoted amide‐directed hydroarylation of aldimines in the presence of a catalytic amount of base gives the corresponding isoindolinone derivatives. A variety of amides and saldimines participated in the present Ru‐catalyzed reaction to furnish the corresponding isoindolinones in moderate to high yield. A variety of amides and aldimines participated in the
Ruthenium-Catalyzed Addition of Aromatic Amides to Internal Alkynes and Subsequent Intramolecular Cyclization for the Atom-Economical Synthesis of Isoindolinones
isoindolinones is described. This novel synthetic strategy involves two catalytic reactions: the ruthenium-catalyzed regioselective alkenylation of aromatic C–H bond of aromatic amides with internalalkynes, and subsequent intramolecular cyclization of the resulting alkene with amide functionalities. The addition of only a catalytic amount of bases is required for efficient construction of the desired
Hydroxoiridium complexes efficiently catalyzed the hydroarylation of alkynes and bicycloalkenes with N-sulfonylbenzamides via C–H activation to give the corresponding ortho-alkenylation and alkylation products in high yields.

The present invention provides compounds of Formula (Ia), and pharmaceutically acceptable salts thereof. The compounds are useful as inhibitors of voltage-gated sodium channels, in particular Nav 1.7. (Ia); as described in the specification. The compounds are useful for the treatment of diseases treatable by inhibition of sodium channels such as pain disorders. Also provided are pharmaceutical compositions containing compounds of the present invention, as well as intermediates and processes useful for making the compounds.
Asymmetric alkylation of N-sulfonylbenzamides with vinyl ethers via a directed C-H bond activation gave high yields of the corresponding addition products with high branch- and enantioselectivity.
