摘要:

手性化合物的结构确定,尤其是新型手性化合物的绝对构型测定一直是不对称研究的重要工作。除单晶测试外,光谱学方法近年来被广泛应用于手性分子结构鉴定,主要包括电子和振动圆二色谱、旋光光谱、旋光拉曼谱等。本文对上述测试方法的原理、应用范围和相关理论计算方法做了介绍。把谱学测试与理论计算相结合,将成为手性分子结构鉴定的重要发展方向。

Abstract:

The determination of the absolute configuration (AC) of chiral compounds, especially the new chiral compounds, is one of the difficulties of the structure determination.The most widely used AC determination chiroptical spectroscopic methods include electronic and vibrational circular dichroism, optical rotatory dispersion, Raman optical activity etc.This mini review summarizes the main test principles, applications and corresponding theoretical calculation methods.With the developments of theoretical chemistry, the AC determination through instrumental characterization technique coupled with quantum chemical calculation, is envisaged to be the new trends of AC assignment.

Key words: Absolute configuration, Theoretical and computational chemistry, Electronic circular dichroism, Vibrational circular dichroism, Optical rotatory dispersion
