Direct access to anthranilic acid derivatives via CO2 incorporation reaction using arynes.
CO2 was found to be directly convertible into anthranilic acid derivatives of great synthetic value through a three-component coupling using arynes and amines. Zwitterions arising from nucleophilic attack of amines to arynes serve as key intermediates in the coupling.
