Literaturverweise

Susceptible to nucleophilic attack, normally at the "acid" 4-carbon. More hindered nucleophiles attack at the "carbamate" 2-carbon. In the presence of DMAP, attack is directed to C-4, giving anthranilic acid derivatives: Synthesis, 266 (1982). For reviews of the chemistry of isatoic anhydrides, including reactions with a wide range of nucleophiles and the formation of a variety of heterocyclic systems, see: Synthesis, 505 (1980); Adv. Heterocycl Chem., 28, 127 (1981).
