Highly efficient temperature-dependent chiral separation with a nucleotide-based coordination polymer

20-Jun-2018 | Rosaria Bruno; Nadia Marino; Lucia Bartella; Leonardo Di Donna; Giovanni De Munno; Emilio Pardo; Donatella Armentano, Chemical Communication, 2018

We report a new chiral coordination polymer, prepared from the cytidine 5′-monophosphate (CMP) nucleotide, capable of separating efficiently (enantiomeric excess of ca. 100%) racemic mixtures of l- and d-Asp in a temperature-dependent manner. The crystal structure of the host–guest adsorbate, ...

Thermo-responsive recoverable polymeric inhibitors for the resolution of racemic amino acids

27-May-2018 | Xichong Ye; Jie Zhang; Jiaxi Cui; Xinhua Wan, Chemical Communication, 2018

Novel polymeric inhibitors with lower critical solution temperatures in water were prepared and used to mediate the crystallization of racemic asparagine monohydrate, leading to chiral separation with 88.6 ee%. They could be recollected by simply elevating the temperature with a high yield of ...

A cationic cyclodextrin clicked bilayer chiral stationary phase for versatile chiral separation in HPLC

25-May-2018 | Jie Zhou; Bo Yang; Jian Tang; Weihua Tang, New Journal of Chemistry, 2018

A cationic cyclodextrin (CD) clicked bilayer chiral stationary phase (CSP) was developed via click chemistry for chiral separations in multimode high-performance chromatography (HPLC). The versatility of this new CSP was evaluated using 17 model racemic pairs including aromatic alcohols, ...

Chiral separation and characterization of triazatruxene-based face-rotating polyhedra: the role of non-covalent facial interactions

24-May-2018 | Pei Zhang; Xinchang Wang; Wei Xuan; Pixian Peng; Zhihao Li; Ruqiang Lu; Shuang Wu; Zhongqun Tian; Xiaoyu Cao, Chemical Communication, 2018

We constructed a series of novel chiral molecular face-rotating polyhedra (FRP) from two 10,15-dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole (triazatruxene) derivatives and trans-1,2-cyclohexane diamine, and investigated how facial interactions and the positions of substituents determine the ...

Enantiomeric separation of six chiral pesticides that contain chiral sulfur/phosphorus atoms by supercritical fluid chromatography

16-Jan-2018 | Lijun Zhan, Yelong Miao, Chunmian Lin, Journal of Separation Science, 2018

Abstract Six chiral pesticides containing chiral sulfur/phosphorus atoms were separated by supercritical fluid chromatography with supercritical CO2 as the main mobile phase component. The effect of the chiral stationary phase, different type and concentration of modifiers, column temperature, ...

Chiral separation of novel iminonaringenin derivatives

15-Jan-2018 | Meriem Bouanini, Nasser Belboukhari, J. Carlos Menéndez, Khaled Sekkoum, Abdelkarim Cheriti, Hassan Y. Aboul‐Enein, Chirality, 2018

Abstract A series of 4‐iminonaringenin derivatives 2‐6 have been prepared in good overall yields from a condensation reaction between naringenin and primary amines. The structures of all products were confirmed by ultraviolet, infrared, proton nuclear magnetic resonance, and carbon‐13 nuclear ...
