On the big screen: A chiral biphenol catalyst screening protocol was developed for the rapid identification of enantioselective nucleophilic boronate reactions with acyl imines (see scheme). The approach successfully identified a unique catalyst for the reaction of aryl, vinyl, and alkynyl boronates. Mechanistic studies demonstrate boronate ligand exchange with the catalyst is necessary for activation
在大屏幕上:开发了一种手性双酚催化剂筛选方案,用于快速鉴定与酰基亚胺的对映选择性亲核硼酸酯反应(参见方案)。该方法成功地确定了一种独特的催化剂,用于芳基、乙烯基和炔基硼酸酯的反应。机理研究表明,硼酸盐配体与催化剂的交换对于亲核加成的活化是必要的。
