The synthesis of N-aryl anthranilic acid derivatives bearing dioxolo, dioxino, cyclopent, and imidazolo supplementary ring systems is reported. The Ullmann-Goldberg condensation of the N-aryl anthranilic acid is improved in yield and reaction time, compared to conventional heating; by ultrasonic irradiation.
