A Simple, Mild, and Practical Method for the Esterification and Thioesterification of Anthranilic Acid Utilizing N-(2-Aminobenzoyl)benzotriazole
摘要:
A convenient and efficient method for the preparation of anthranilic esters and anthranilic thioesters has been developed by the treatment of N-(2-aminobenzoyl)benzotriazoles with alcohols and thiols in the presence of 4-(dimethylamino)pyridine (DMAP).

A ruthenium(II)-catalyzed coupling reaction of isatoicanhydrides and salicylaldehydes has been developed for the synthesis of 2-aminobenzoates. This reaction proceeds through metal-catalyzed decarbonylation and decarboxylation to afford good yields of aryl 2-aminobenzoates.
