Figure 5.9
Synthetic approach (II) for amylose-grafted silica gel.
The
chiral
recognition
abilities
of
these
materials
were
investigated using racemic molecules, e.g.,
-stilbene oxide by
HPLC. Consequently, the enantiomers eluted at different retention
times, indicating that racemic
trans
trans
-stilbene oxides were completely
separated.
