Enantioselective Quantification of Amphetamine and Metabolites in Serum Samples: Forensic Evaluation and Estimation of Consumption Time

Metabolites, 2021
In forensic toxicology, amphetamine intoxications represent one of the most common case groups and present difficult questions for toxicologists. Estimating the time of consumption and the current influence of the stimulant is particularly difficult when

Distinguishing left- and right-handed molecules by two-step coherent pulses

, 2010
Chiral molecules with broken parity symmetries can be modeled as quantum systems with cyclic-transition structures. By using these novel properties, we design two-step laser pulses to distinguish left- and right-handed molecules from the enantiomers ...

Chiral separation by ligand-exchange

Macedonian Journal of Chemistry and Chemical Engineering, 2011
The principle of chiral ligand-exchange, introduced by Davankov, has become a widely used technique for chiral separation in both chromatography and in electromigration techniques.

Substituted Aryl Benzylamines as Potent and Selective Inhibitors of 17β-Hydroxysteroid Dehydrogenase Type 3

Molecules, 2021
17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) is expressed at high levels in testes and seminal vesicles; it is also present in prostate tissue and involved in gonadal and non-gonadal testosterone biosynthesis.

The diastereoselective Meth-Cohn epoxidation of camphor-derived vinyl sulfones [PDF]

, 2012
Some camphor-derived vinyl sulfones bearing oxygen functionality at the allylic position have been synthesized and their nucleophilic epoxidation reactions under Meth-Cohn conditions have been explored.

Enantioseparation of organometallic compounds and metal complexes by liquid chromatographic techniques. A review

Journal of Chromatography Open
Chiral organometallic compounds and metal complexes, and more recently metal clusters, have attracted great interest for applications in chemical, biological, medical, and material sciences. In these fields, liquid chromatography has been widely used for

Bottom-up synthesis of chiral covalent organic frameworks and their bound capillaries for chiral separation

Nature Communications, 2016
Porous materials can be used in columns for gas separation applications. Here, Yan and co-workers from a bottom-up method have produced chiral covalent organic frameworks and from an in situ strategy formed capillary columns for chiral gas chromatography.

Preparation of anti-vicinal amino alcohols: asymmetric synthesis of D-erythro-Sphinganine, (+)-spisulosine and D-ribo-phytosphingosine [PDF]

, 2013
Two variations of the Overman rearrangement have been developed for the highly selective synthesis of anti-vicinal amino alcohol natural products. A MOM-ether directed palladium(II)-catalyzed rearrangement of an allylic trichloroacetimidate was used as ...
