types of chiroptical spectroscopies, namely, optical rotatory dispersion (ORD), electronic circular dichroism (ECD), and vibrational circular dichroism (VCD), were applied to enantiomeric compounds. Through comparison with Density Functional Theory (DFT) calculations, encompassing extensive conformational analysis, full assignment of the absolute configuration (AC) for the three sets of compounds was obtained
三种潜在的A 3腺苷受体拮抗剂的对映体对的手性分离:(R / S)-N-(6-(1-苯乙氧基)-2-(丙硫基)嘧啶-4-基)乙酰胺(1),(R / S)-N-(2-(1-苯乙硫基)-6-丙氧基嘧啶-4-基)乙酰胺(2)和(R / S)-N-(2-(苄硫基)-6-仲丁氧基嘧啶- 4-基)乙酰胺(3)是通过高效液相色谱(HPLC)实现的。三种类型的手性光谱学,即旋光色散(ORD),电子圆二色性(ECD)和振动圆二色性(VCD),被用于对映体化合物。通过与密度泛函理论(DFT)的计算比较,包括广泛的构象分析,获得了三组化合物的绝对构型(AC)的完全分配。手性28:434–440,2016。©2016 Wiley Periodicals,Inc.
