Fecha de publicación: | 29-oct-2009 | Citación: | Organic Letters 2009, 11, 4938-4941 | Resumen: | The first examples of the direct arylation of benzo-fused 1,4-quinones by the dicationic Pd(II)-catalyzed addition of arylboronic acids are reported. The addition reaction is carried out under very mild conditions (dioxane-H2O, rt, open air atmosphere) and is tolerant of free OH groups. In addition, the reaction shows high regioselectivity when using nonsymmetrical quinones as starting materials. | URI: | http://hdl.handle.net/10261/18173 | DOI: | 10.1021/ol902084g | ISSN: | 1523-7060 |
