In this article, we describe the development and 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,我们描述了新设计的C(2)-对称双异羟肟酸(BHA)配体的开发及其初步结果,以及这些新配体在钒催化的烯丙醇和高烯丙醇不对称环氧化反应中的应用。基于这一成功,我们展示了BHA在钼催化的未官能化烯烃和硫化物不对称氧化反应中的多功能性。
