Lemon Juice: An Environmentally Benign Catalyst for Synthesis of Benzothiazoles and Benzoxazole Derivatives in Aqueous Medium

Lemon juice as a natural and eco-friendly catalyst has been utilized for the synthesis of benzothiazole and benzoxazole derivatives by the reaction of 2-aminothiophenol or 2-aminophenol with a variety of aryl aldehydes in good-excellent yields. The beneficial features of this new synthetic approach include short reaction time, a clean reaction profile with mild reaction condition and an easy work up procedure.
