A method for the purification of alcohols from organic soluble impurities has been discovered comprising treating the crude alcohol with a cyclic anhydride followed by an aqueous base and extracting the corresponding half-ester into aqueous solution leaving the impurities in organic solution. This method is particularly useful for the separation of chiral, nonracemic alcohols from the corresponding antipodal ester (the mixture resulting from an enzymatic kinetic resolution) because the separation is non-chromatographic and the enantiomeric integrity of the products is maintained.
已发现一种从有机可溶杂质中纯化醇的方法,包括用环酐处理粗醇,然后用
水性碱处理,并将相应的半酯提取到
水溶液中,将杂质留在有机溶液中。这种方法特别适用于从相应的对映体酯(从酶动力学分辨产生的混合物)中分离手性、非拉克米醇,因为分离是非色谱的,产品的对映体完整性得以保持。
