A new class of bicyclic O,P ligands has been prepared and evaluated in the 1,4-addition to α,β-unsaturated ketones. The best results with the bicyclic ligand were obtained using a lower catalyst loading than what has been reported with similar ligands when adding a Grignard reagent to 2-cyclohexenone.
已经制备了新型的双环O,P配体,并在α ,β-不饱和酮的1,4-加成中进行了评估。当向2-环己烯酮中添加格氏试剂时,与使用类似配体的催化剂相比,使用双环配体获得的最佳结果的催化剂负载量更低。
