Nickel-Catalyzed Cycloaddition of Anthranilic Acid Derivatives to Alkynes
摘要:
A nickel-catalyzed cycloaddition has been developed where readily available anthranilic acid derivatives react with alkynes to afford substituted indoles. The reaction involves oxidative addition of Ni(0) to an ester moiety, which allows intermolecular addition to alkynes via decarbonylation and 1,3-acyl migration.

Herein we report a strategy concerning Rh(III)-catalyzed direct ortho-C–H bond carbonylation to construct benzoxazinones fromanilines and their derivatives with high atom economy. Interestingly, the corresponding amides were generated in situ fromanilines when excess Ac2O was added and directed the following C–H bond carbonylation to form benzoxazinones. Extensive functional group tolerance can be
