An efficient and metal-free protocol for direct oxidation of secondary amines to nitrones has been developed, using Oxone in a biphasic basic medium as the sole oxidant. The method is general and tolerant with other functional groups or existing stereogenic centers, providing rapid access to enantiomerically pure compounds in good yields.
使用双相碱性介质中的Oxone作为唯一氧化剂,已开发出一种有效的,不含金属的方案,可将仲胺直接氧化为硝酮。该方法是通用的,并且对其他官能团或现有的立体异构中心具有耐受性,可快速获得对映体纯的化合物,收率很高。
