| Abstract: | Two chiral crown ethers containing end-alkenyl groups have been synthesized by the use of Dmannitol and (+)-2-amino-1-butanol as chiral sources. They were anchored onto polyhydromethyl-siloxanes by hydrosilylation reaction, rendering two novel chiral polysiloxane stationary phases chirasil-man-18C6-25and chirasil-aza-15C5-25. The chromatographic properties and separation ability of these two phases for enantiomers have been studied. The chirasil-man-18C6-25 phase has efficient thermostability and considerable enantiomer-xesolving power for racemics which have hydrogen-bonding force such as a-phenylacetol and phenylalanine isopropylester. |
