A novel method for the synthesis of various trisubstituted oxazoles (28 examples, up to 88% yield) has been developed using 9H-thioxanthen-9-one (TX) mediated oxidative annulation of N-acetyl enamide under visible light irradiation in the presence of BF3 center dot Et2O (2.0 equiv) and 40 mol% of PhNO2. This metal-free procedure offers high atom and step economy, environmentally friendly and mild conditions, and a broad range of applicable substrates.
