High yield synthesis of quinoline-based fluorescent imines, exhibiting the highest Stokes shift exceeding 380 nm (> 18 000 cm(-1)), is reported in the current publication. Such large difference in the excitation and emission wavelengths is quite unusual. Synthesis of imines was accelerated by ultrasound. Both experimental and theoretical studies have been performed.
Activated Fly Ash Catalyzing the Synthesis of Novel Potent 4-Thiazolidinones of 4-Amino Antipyrine Anils Using CEM Discover Microwave Methodology and Their Virtual Screening
waste, has been used as an efficient and cost-effective activating catalyst for the synthesis of new potent thiazolidinones (4a–n), starting from imine (3a–n) and thioacetic acid. The reactions were performed under CEM Discover microwave irradiation in solvent-free conditions. This reaction is scalable to a multigram scale and the methodology has resulted in an efficient synthesis. Herein, a benign
