A general method based on difference circular dichroic (DIF CD) spectroscopy for assigning the absolute configuration of 1,2,4-triol is presented. Four possible stereoisomers of 6-heptene-1,2,4-triol were prepared and served as models to develop the procedure. The sign of the DIF CD Cotton effect is correlated to the absolute configuration of the C2 position.
提出了一种基于差圆二向色(DIF CD)光谱法确定1,2,4-三醇绝对构型的通用方法。制备了四种可能的6-庚烯-1,2,4-三醇立体异构体,并将其用作开发该方法的模型。DIF CD棉花效应的迹象与C2位置的绝对构型相关。
