A novel biselector bonded‐type multifunctional chiral stationary phase (MCSP) was prepared by covalently crosslinking dialdehyde cellulose (DAC) with 6‐monodeoxy‐6‐monoamino‐β‐cyclodextrine (CD) via Schiff base reaction. The biselector bonded‐type MCSP had good chiral and achiral chromatographic performance in normal phase (NP) and reversed phase (RP) modes. Seven and eight enantiomers were successfully...
A novel high‐performance liquid chromatography (HPLC) multifunctional immobilized chiral stationary phase was prepared by bonding dialdehyde microcrystalline cellulose to aminosilica via Schiff base reaction and then derivatized with 3,5‐dimethylphenyl isocyanate. The HPLC multifunctional immobilized chiral stationary phase could not only achieve chiral separation but also achieve achiral separation...
The pharmacokinetics of diniconazole enantiomers in quail (Coturnix coturnix japonica) were investigated by liquid chromatography‐tandem mass spectrometry (LC‐MS/MS). Quails were exposed to racemic diniconazole in capsule by oral at dose of 10 mg/kg (body weight). The maximal concentrations observed in blood, heart, liver, and kidney were 3.18, 11.35, 12.32, 15.03 µg/g for S‐diniconazole, and 1.13,...
The enantioselective bioaccumulation of diniconazole in Tenebrio molitor Linne larva was investigated with liquid chromatography tandem mass spectrometry based on the ChiralcelOD‐3R[cellulose tri‐(3,5‐dimethylphenyl carbamate)] column. In this study we documented the effects of dietary supplementation with wheat bran contaminated by racemic diniconazole at two dose levels of 20 mg kg‐1 and 2 mg kg...
Two couples of enantiomeric platinum(II) complexes: Pt(L1a)Cl (1a), Pt(L1b)Cl (1b) and Pt(L1a)(C ≡ C − Ph) (2a), Pt(L1b)(C ≡ C − Ph) (2b) (L1a = (+)‐1,3‐di‐(2‐(4,5‐pinene)pyridyl)benzene, L1b = (−)‐1,3‐di‐(2‐(4,5‐pinene)pyridyl)benzene) were synthesized and characterized. Their absolute configurations were determined by single crystal X‐ray diffraction and further verified by circular dichroism (CD)...
Novel copper(II) coordination compounds with chiral macrocyclic imine ligands derived from R‐/S‐camphor were asymmetrically synthesized and characterized with the aid of chiroptical spectroscopies. Crystal structures of both enantiomers were determined by single crystal X‐ray diffraction analysis. Circular dichroism (CD) spectra were analyzed using a simplified exciton model as well as quantum chemical...
