New Vistas in Quinoline Synthesis. -Ga/B-mediated reaction of anilines with nitriles allows a practical and rapid access to 2-aminoaryl ketones. Coupling of the latter with β-keto carbonyl compounds and sulfones provides a general method to prepare 2,3,4-trisubstituted quinolines. Reaction of the benzoxazinone (XIV) with keto sulfones also results in efficient formation of quinolines. -(ATECHIAN, S.; NOCK, N.; NORCROSS, R. D.; RATNI, H.; THOMAS, A.

Addition reactions O 0060 Task Specific Onium Salts (TSOSs) as Efficient Soluble Supports for Zard RadicalAddition to Olefins. -Intermolecular radical additions of xanthates to olefins are investigated with reactants bearing a soluble ammonium-substituted support. The results are by far superior to those reported with other soluble supports. -(VERRON, J.; JOERGER, J.-M.; PUCHEAULT, M.; VAULTIER*, M.; Tetrahedron Lett. 48 (2007) 23, 4055-4058; UMR, CNRS, Univ.
