Ex‐changing places: A highly enantioselective desymmetrization of 1,2‐diols has been developed in which the catalyst utilizes reversible covalent bonding to the substrate to achieve both high selectivity and rate acceleration (see scheme, PMP=pentalmethylpiperidine, TBS=tert‐butyldimethylsilyl). Induced intramolecularity is responsible for the enhanced rate, thus allowing the reaction to be performed at
交换位置:已开发出 1,2-二醇的高度对映选择性去对称化,其中催化剂利用与底物的可逆共价键来实现高选择性和速率加速(参见方案,PMP=五甲基哌啶,TBS=叔丁基二甲基甲硅烷基)。诱导的分子内性是提高速率的原因,因此可以在室温下进行反应。
