Chiral separation with novel (S)-biotin-bonded silica gel for liquid chromatography.
Liquid chromatographic separation of enantiomers was accomplished using a chiral stationary phase (CSP) derived from (S)-biotin on silica gel. In both nonaqueous and aqueous media, this CSP (1) permitted separation of racemic amino acid derivatives based on hydrogen bonding with a urea moiety of the biotin moiety.
