This work describes an expeditious and efficient preparation of enantiopure (thiolan-2-yl)diphenylmethanol (2) featuring a double nucleophilic substitution and Shi epoxidation as key steps. One of the applications of its benzyl ether derivative to asymmetric sulfur ylide-mediated epoxidation with up to 92% ee (14 examples) was also demonstrated herein.
这项工作描述了快速和有效的对映体纯(thiolan-2-yl)二苯甲醇(2)的制备,其特征在于双亲核取代和Shi环氧化是关键步骤。本文还证明了其苄基醚衍生物在不对称的硫代叶酸介导的环氧化中的应用之一,其中ee高达92%(14个实例)。
