A number of CF3-substituted carbinols decorated with an azine donor are efficiently prepared from fluoral and kinetically resolved in a reagent-controlled, CuâH-catalysed SiâO coupling with a chiral silane. Selectivity factors are high, indicating a larger steric effect than CH3 or C6H5groups.
通过试剂控制、CuâH 催化、SiâO 与手性硅烷偶联的方法,从氟中高效制备出了一些以偶氮供体为装饰的 CF3 取代的炔醇,并对其进行了动力学解析。选择性系数很高,表明立体效应大于 CH3 或 C6H5 基团。
