Organocatalytic desymmetrization provides access to planar chiral [2.2]paracyclophanes

Nature Communications
Planar chiral [2.2]paracyclophanes consist of two functionalized benzene rings connected by two ethylene bridges. These organic compounds have a wide range of applications in asymmetric synthesis, as both ligands and catalysts, and in materials science ...

Design criteria for dense permeation-selective membranes for enantiomer separations

, 2001
Dense enantioselective membranes can distinguish between two enantiomers by different mechanisms. At this moment, it is not clear which mechanism provides the best membranes for large-scale enantiomer separations.

Chiral Separation of Mandelic Acid Derivatives Using Various Permethylated Cyclodextrin Selectors Containing Stationary Phases in GC

Molecules
A good chiral separation usually results in a trial-and-error process; however, through systematic studies, certain principles can be established to correlate structure with chiral selectivity.

Emergence of a Luttinger liquid phase in an array of chiral molecules

Physical Review Research
We propose a robust platform for simulating chiral quantum magnetism using linear arrays of trapped asymmetric-top molecules, specifically 1,2-propanediol (C_{3}H_{8}O_{2}).

First separation of commendamide enantiomers

Journal of Pharmaceutical and Biomedical Analysis
N-(3-hydroxyacyl)glycines are compounds of remarkable interest due to their biogenic origin and bioactivity and as precursors of the corresponding 3-acyloxy derivatives which represent an important class of bioactive products of bacterial origin. Commendamide [N-(3-hydroxypalmitoyl)glycine] (1) is a gut microbiota-derived bioactive metabolite that is ...

A comparison of medetomidine and its active enantiomer dexmedetomidine when administered with ketamine in mice [PDF]

, 2013
Medetomidine-ketamine (MK) and dexmedetomidine-ketamine (DK) are widely used to provide general anaesthesia in laboratory animals, but have not been compared directly in many of these species, including rodents.
