研究了(R)-苯并四咪唑催化的一系列α-位带有各种官能团的苄醇类化合物的拆分.通过对反应结果的分析,推导出此类底物拆分反应中存在的竞争性不对称诱导模型.苯环与催化剂的cation-π相互作用和官能团π-体系与催化剂的相互作用会产生两种不同的、相互竞争的过渡态,两种过渡态并存导致立体选择性降低及产物构型的改变. The resolution of a series of α-position benzyl alcohols with various functional groups catalyzed by (R) -benzotetrazole was studied. By analyzing the reaction results, the existence of Competitive asymmetric induction model.The cation-π interaction between benzene ring and catalyst and the interaction between functional group π-system and catalyst produce two different and competing transition states, and the coexistence of the two transition states leads to the decrease of stereoselectivity And product configuration changes.
