This work deals with the synthesis of two mixed binary chiral selectors prepared by grafting L– or D-valine tert-butylamide on permethylated cyclodextrin macrocycle. The enantioselective properties of the new chiral selectors diluted in OV11 polysiloxane (35% phenyl- and 65% methylsiloxane) were studied by injections of 117 racemic mixtures The mixed chiral selectors with L-valine and, to a lesser extent with D-valine, have an improved enantioselectivity toward amino acid derivatives by comparison to permethylated cyclodextrin. The enantioseparation capability of these new chiral selectors proved to be slightly less efficient than Chirasil-L-Val (Alltech) for amino acid derivatives, but it was extended to include terpenes, lactones, esters, aliphatic compounds and aryl alcs. In the experiment, the researchers used many compounds, for example, (S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4Product Details of 171032-87-4).

(S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Product Details of 171032-87-4
