Chiral nucleophilic catalysts, 6-aryl-phenyl-dihydroimidazoquinolines (PIQs), were designed, synthesised and applied to the kinetic resolution of arylalkyl carbinols with very high selectivity (S) factors (up to 530). Density functional theory calculations indicate that multiple noncovalent interactions play a key role in chiral recognition between 6-aryl-PIQ catalysts and chiral secondary alcohol
设计,合成了手性亲核催化剂6-芳基-苯基-二氢咪唑并喹啉(PIQs),并以很高的选择性(S)因子(最高530)将其用于芳基烷基甲醇的动力学拆分。密度泛函理论计算表明,多个非共价相互作用在6-芳基-PIQ催化剂与手性仲醇底物之间的手性识别中起关键作用。
