| Abstract: | Two amide-type chiral moieties containing end-alkenes and rigid unit of phenyl group were synthesized using L-phenylalanine and L-valine as chiral sources, and two novel chiral polysiloxanes were prepared by hydrosilylating these moieties onto polyhy-dromethylsiloxanes. This method was found to be extensively applicable to make chiral amidepolysiloxane phase; and it provides some advantages: they are straightforward and have high yield for each synthetic pathway. The prepared chiral phases own good chro-matographic property and effective enantiomer separation ability as well as good thermosta-bility. |
