To successively construct two amide bonds between two benzene rings, the reaction of methyl N-alkylanthranilate and N-alkylisatoic anhydride in the presence of a base was studied. When the reaction was carried out with lithium hexamethyldisilazide and N,N,N,N-tetramethylethylenediamine in THF at 70 °C under reduced pressure, a cyclic diamide was obtained in high yield.
Reactions of Anthranilium Salts with Nucleophiles: Adduct Formation and Rearrangement

3-Unsubstituted anthranilium salts 1 react with alcohols in the presence of bases to yield adducts 5 which rearrange to the esters 4 when refluxed in xylene.Similar processes involving 1 and cyanide or azide also have been observed.Evidence favoring benzoazetinones 2 as rearrangement intermediates is presented.The chemistry of 1 with phosphines and phosphites is also described.For example, treatment of 1c with trimethyl phosphite yields the rearranged adduct salt 14 which cleaves to the acyl phosphonate 15 when treated with triethylamine.
