Interface Chirality: From Biological Effects to Biomedical Applications.
Publication Type: Academic Journal
Source(s): Molecules. Aug2023, Vol. 28 Issue 15, p5629. 18p.
Abstract: Chiral surface is a critical mediator that significantly impacts interaction with biological systems on regulating cell behavior. To better understand how the properties of interfacial Chirality affect cell behavior and address the limitations of chira...
Reaction of Triazolic Aldehydes with Diisopropyl Zinc: Chirality Dissipation versus Amplification.
Publication Type: Academic Journal
Source(s): Symmetry (20738994). Jul2023, Vol. 15 Issue 7, p1382. 13p.
Abstract: The phenomenon of amplifying asymmetric autocatalysis (AAA) has recently been restricted to alkylation of several specific substrates with diisopropyl zinc (Soai reaction). Targeting the extension of the scope of this phenomenon, we studied the reactio...
Chiral symmetry breaking: Current experimental status and prospects.
Publication Type: Conference
Source(s): EPJ Web of Conferences. 4/3/2023, Vol. 282, p1-8. 8p.
Abstract: Chiral symmetry, linked to the smallness of the quark masses compared to the QCD bound states, and its breaking pattern are exploited in effective field theory to describe a multitude of phenomena by a few low-energy constants. Those concern light-meso...
Laser-Induced Chirality of Plasmonic Nanoparticles Embedded in Porous Matrix.
Publication Type: Academic Journal
Source(s): Nanomaterials (2079-4991). May2023, Vol. 13 Issue 10, p1634. 12p.
Abstract: Chiral plasmonic nanostructures have emerged as promising objects for numerous applications in nanophotonics, optoelectronics, biosensing, chemistry, and pharmacy. Here, we propose a novel method to induce strong chirality in achiral ensembles of gold ...
Palladium-Catalyzed Stereoselective Construction of 1,3-Stereocenters Displaying Axial and Central Chirality via Asymmetric Alkylations.
Publication Type: Academic Journal
Source(s): Molecules. Apr2023, Vol. 28 Issue 7, p2927. 15p.
Abstract: The concurrent construction of 1,3-stereocenters remains a challenge. Herein, we report the development of stereoselective union of a point chiral center with allenyl axial chirality in 1,3-position by Pd-catalyzed asymmetric allenylic alkylation betwe...
Elimination of Chirality in Three-Dimensionally Confined Open-Access Microcavities.
Publication Type: Academic Journal
Source(s): Nanomaterials (2079-4991). Jun2023, Vol. 13 Issue 12, p1868. 12p.
Abstract: The emergent optical activity (OA) caused by anisotropic light emitter in microcavities is an important physical mechanism discovered recently, which leads to Rashba–Dresselhaus photonic spin-orbit (SO) coupling. In this study, we report a sharp contra...
Desymmetrization of Prochiral N -Pyrazolyl Maleimides via Organocatalyzed Asymmetric Michael Addition with Pyrazolones: Construction of Tri- N -Heterocyclic Scaffolds Bearing Both Central and Axial Chirality.
Publication Type: Academic Journal
Source(s): Molecules. Jun2023, Vol. 28 Issue 11, p4279. 22p.
Abstract: The desymmetrization of N-pyrazolyl maleimides was realized through an asymmetric Michael addition by using pyrazolones under mild conditions, leading to the formation of a tri-N-heterocyclic pyrazole–succinimide–pyrazolone assembly in high yields with...
Atropselective Organocatalytic Synthesis of Chiral Compounds Containing Nitrogen along the Axis of Chirality.
Publication Type: Academic Journal
Source(s): Symmetry (20738994). Jun2023, Vol. 15 Issue 6, p1261. 27p.
Abstract: Atropisomers, i.e., stereoisomers that are distinct because their free rotation about a single bond is hindered by steric interactions between nearby bulky groups or by electrostatics, may interact with their surroundings in different ways, and may als...
Single Photon Approach for Chirality Sensing.
Publication Type: Academic Journal
Source(s): Photonics. May2023, Vol. 10 Issue 5, p512. 10p.
Abstract: We developed a high sensitivity optical sensor for circular birefringence using a heralded photon source. The sensor can be employed for chirality measurements and, being based on single photons, can be exploited for fragile biological sample or in met...
Chirality induced spin selectivity: A classical spin-off.
Publication Type: Academic Journal
