• General Description: Amylose is a linear polysaccharide composed of α-1,4-linked glucose units, known for its helical structure and ability to form inclusion complexes, which makes it useful in chiral recognition applications. In this study, amylose derivatives, specifically 3,5-dimethylphenylcarbamates with 4-(trimethoxysilyl)phenylcarbamate groups, were synthesized and immobilized on silica gel to create chiral stationary phases (CSPs) for HPLC. These CSPs demonstrated high enantioselectivity, comparable to commercial immobilized phases, particularly when small amounts of the 4-(trimethoxysilyl)phenyl groups were incorporated, highlighting amylose's effectiveness in chiral separation.

Immobilization and chiral recognition of 3,5-dimethylphenylcarbamates of cellulose and amylose bearing 4-(trimethoxysilyl)phenylcarbamate groups

10.1002/chir.20722

The study focused on the immobilization and chiral recognition of cellulose and 3,5-dimethylphenylcarbamate of amylose with 4-(trimethoxysilyl)phenylcarbamate groups. The aim of this study was to synthesize these chiral stationary phases (CSPs) using a one-pot method and immobilize them on silica gel for use in high performance liquid chromatography (HPLC). The researchers investigated the effect of the number of 4-(trimethoxysilyl)phenyl groups on the immobilization efficiency and enantiomeric separation. They found that the introduction of small amounts of these groups resulted in CSPs with high chiral recognition, comparable to commercially available immobilized CSPs.
