Ultrasonic irradiation of the Ullmann condensation: Application to the preparation of dioxolo, dioxino, cyclopent, and imidazolo anthranilic acid derivatives

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, compar

Pyridinium Betaines Derived from Thiazolo and Imidazoacridinones

Four betaines derived from imidazo[4,5-a], imidazo[5,4-a] and thiazolo[5,4-a]acridine have been prepared in a six step procedure starting from 2-chlorobenzimidazoles and benzothiazoles. The 1H and 133C nmr has been used to characteri
