In order to develop new type of chiral separation materials, in this study, 6‐amino‐6‐deoxyamylose was used as chiral starting material with which 10 derivatives were synthesized. The amino group in 6‐amino‐6‐deoxyamylose was selectively acylated and then the hydroxyl groups were carbamoylated yielding amylose 6‐amido‐6‐deoxy‐2,3‐bis(phenylcarbamate)s, which were employed as chiral selectors (CSs)...
(2S,3S)‐2,3‐Bis(3,5‐dimethylphenylcarbonyloxy)‐3‐(benzyloxycarbonyl)‐propanoic acid and (2S,3S)‐2,3‐bis(1‐naphthalenecarbonyloxy)‐3‐(benzyloxycarbonyl)‐propanoic acid were synthesized from D‐tartaric acid. These two compounds were chlorinated to afford two chiral selectors for chiral stationary phases (CSPs). The selectors were separately immobilized on aminated silica gel to give two single selector...
L‐Dibenzoyl tartaric acid was mono‐esterified with benzyl alcohol, and then chlorinated with SOCl2 to give (2S,3S)‐1‐(benzyloxy)‐4‐chloro‐1,4‐dioxobutane‐2,3‐diyl dibenzoate (Selector 1). (1R,2R)‐1,2‐Diphenylethylenediamine was mono‐functionalized with phenyl isocyanate and phenylene diisocyanate in sequence to give (1R,2R)‐1,2‐diphenyl‐2‐(3‐phenylureido)ethyl 4‐ isocyanatophenylurea (Selector 2)...
In our recent work, a series of dendritic chiral stationary phases (CSPs) were synthesized, in which the chiral selector was L‐2‐(p‐toluenesulfonamido)‐3‐phenylpropionyl chloride (selector I), and the CSP derived from three‐generation dendrimer showed the best separation ability. To further investigate the influence of the structures of dendrimer and chiral selector on enantioseparation ability, in...
