describe a one-pot method to obtain a variety of 2-arylbenzoxazinones and N-benzoyl anthranilic acid by using a copper catalyst and molecular oxygen as oxidants. This protocol involves tandem cyclization and oxidative processes of 2-alkynylanilines to afford significant motifs in synthetic and medicinal chemistry with moderate yields. We also demonstrated that combining the Sonogashiracoupling and the

Palladium (0)-catalyzed Ortho-benzoxylation of the sp2 C–H bond of arylbenzoxazinones with carboxylic acid is reported. With benzoxazinone as directing group, the reaction went smoothly under the benign condition and gave the desired product with excellent ortho selectivity. This procedure is compatible with a wide range of functional groups without the use of any ligands or additives. This method

way to synthesise 2-aryl-4H-benzo[d][1,3]oxazin-4-ones has been developed by the cyclisation of Schiff bases with (diacetoxyiodo)benzene. The salient features of this new protocol which starts from an anthranilic acid and an aromatic aldehyde, are short reaction time, mild reaction conditions and good yields.
