Asymmetric synthesis of β-amino cyanoesters with contiguous tetrasubstituted carbon centers by halogen-bonding catalysis with chiral halonium salt

Beilstein Journal of Organic Chemistry
β-Amino cyanoesters are important scaffolds because they can be transformed into useful chiral amines, amino acids, and amino alcohols. Halogen bonding, which can be formed between halogen atoms and electron-rich chemical species, is attractive because ...

Chirally locked and dynamic bis-perylene diimide macrocycles with multiple sources of chirality

Communications Chemistry
Chiral organic materials show great promise in optoelectronics, sensing and catalysis. Among those, macrocycles are of great interest due to their preorganisation and potential amplification of chiroptical properties.

Chiral phosphoric acid-catalyzed asymmetric synthesis of helically chiral, planarly chiral and inherently chiral molecules

Beilstein Journal of Organic Chemistry
Chiral molecules, distinguished by nonsuperimposability with their mirror image, play crucial roles across diverse research fields. Molecular chirality is conventionally categorized into the following types: central chirality, axial chirality, planar ...

Examples of dynamic chirality in nuclei

EPJ Web of Conferences, 2018
In many cases the chirality was almost observed but the transition probabilities are different. This fact is clearly seen in the cases of 134Pr and 102Rh. In the case of chirality, the yrast and the side bands should be nearly degenerate.

Chiral sensors

TrAC Trends in Analytical Chemistry, 2019
Chirality has a crucial effect on clinical, chemical and biological research since most bioactive substances possess chirality in the natural world. Thus, new effective methods and/or (nano)materials are required to explain chiral recognition of chiral substances, which always become a hot topic in pharmaceutical and chemo/biological study.

Use of a new micropattern tape method to detect chirality shifts in differentiating C2C12 cells.

PLoS ONE
Chirality is an intrinsic property of cells manifested as left-right (LR) asymmetry in terms of cellular morphology and organization, which influences cell behavior, migration, and tissue development.

Chiral mixtures [PDF]

Journal of Mathematical Physics, 2002
An index evaluating the amount of chirality of a mixture of colored random variables is defined. Properties are established. Extreme chiral mixtures are characterized and examples are given. Connections between chirality, Wasserstein distances, and least squares Procrustes methods are pointed out.

Spin-Selective Transmission and Devisable Chirality in Two-Layer Metasurfaces

Scientific Reports, 2017
Chirality is a nearly ubiquitous natural phenomenon. Its minute presence in most naturally occurring materials makes it incredibly difficult to detect.
