preliminary results of our new designed C(2)-symmetric bis-hydroxamic acid (BHA) ligands and the application of the new ligands for vanadium-catalyzed asymmetric epoxidation of allylic alcohols as well as homoallylic alcohols. From this success we demonstrate the versatile nature of BHA in the molybdenum catalyzed asymmetric oxidation of unfunctionalized olefins and sulfides.
在本文中,我们描述了我们新设计的 C(2)-对称双异羟肟酸 (BHA) 配体的开发和初步结果,以及新配体在钒催化烯丙醇和高烯丙醇不对称环氧化中的应用. 从这一成功中,我们证明了 BHA 在钼催化的非官能化烯烃和硫化物的不对称氧化中的多功能性。
