Abstract
An environmentally benign and economic synthesis of 6H-2-amino-4,6-diaryl-1,3-thiazines (4a-g) is described from readily accessible substituted chalcones (1a-g) and thiourea (2) in presence of base and ethanol as energy transfer medium by exposure to microwaves. The reaction time has been brought down from hours to seconds with improved yield as compared to conventional heating. All the synthesized compounds were tested for their antibacterial, herbicidal, fungicidal, insecticidal and animal health activity.
