3-Aryllawsones are well known for their wide range of applications in medicinal chemistry, but their synthesis has always remained challenging as no comprehensive protocol has been outlined to date.
The palladium(II) acetate catalyzed reaction of phenyliodonium ylides of 2-hydroxyquinones with arylboronicacids affords a variety of 3-substituted 2-hydroxyquinone derivatives. Best yields are obtained by using tri(tert-butyl)phosphine as a ligand.
乙酸钯 (II) 催化 2-羟基醌的苯基碘鎓叶立德与芳基硼酸反应得到多种 3-取代的 2-羟基醌衍生物。使用三(叔丁基)膦作为配体可获得最佳产率。
