摘要
将合成产品菊酸乙酯和菊酸冰片酯水解后 ,重新酯化成菊酸 - 1薄荷酯 ,利用毛细管柱色谱分离检测其光学异构体的含量 ,可得到d -反式菊酸、1-反式菊酸、顺式外消旋菊酸的相对含量 ,并由此计算出菊酸不对称催化合成反应中顺、反菊酸的比例、菊酸乙酯、菊酸冰片酯的反式的对映体超量为 :7 79%和 15 84%。
In this paper,by hydrolysis and reesterification with 1-menthol,chrysanthemate products which were obtained by asymmetric synthesis were converted into the diastereomers.By the capillary gas chromatographic technology,d-trans、1-trans、dl-cisisomer and trans-enantiomer excess of the products were determinated.
