The synthesis of new chiral tridentate ligands is reported which coordinate transition metals in a meridional way. The ligands contain a pyridine ring, an oxazoline ring, and a strongly coordinating diphenylphosphanyl group. The methionine-derived ligand forms a copper complex, which has been studied by X-ray crystallography. The new ligands were tested in models of enantioselective catalyses, such
据报道,新的手性三齿配体的合成以子午方式配位过渡金属。所述配体包含吡啶环,恶唑啉环和强配位的二苯基膦基。蛋氨酸衍生的配体形成铜络合物,已通过X射线晶体学对其进行了研究。在对映选择性催化剂的模型中测试了新的配体,例如对酮内酯内酯的氢化,苯乙酮的氢化硅烷化以及对苯乙酮的转移氢化。
