Probability rule for chiral recognition

Chirality, 2004
AbstractMolecular Chirality is of central interest in biological studies because enantiomeric compounds, while indistinguishable by most inanimate systems, show profoundly different properties in biochemical environments. Enantioselective separation methods, based on the differential recognition of two optical isomers by a chiral selector, have been ...

Chiral Recognition in Surface Explosion

Journal of the American Chemical Society, 2004
The vast majority of chiral compounds crystallize into racemic crystals. It has been predicted and was experimentally established as a rule that chiral molecules on surfaces are more easily separated into homochiral domains due to confinement into a plane and lower entropic contributions.

Chiral Recognition in Cucurbituril Cavities

Journal of the American Chemical Society, 2006
For the first time, achiral cucurbiturils (CBs) were endowed with significant enantiomeric and distereomeric discrimination by incorporating a strong chiral binder. Calorimetric, nuclear magnetic, light-scattering, and mass spectral studies revealed that (S)-2-methylbutylamine (as a strong binder) can be discriminated by two enantiomeric supramolecular

Enantiomeric Water-Soluble Octopus[3]arenes for Highly Enantioselective Recognition of Chiral Ammonium Salts in Water.

Angewandte Chemie, 2022
Study of enantioselective recognition in water by synthetic chiral macrocyclic receptors is undoubtedly of theoretical and practical significance, but it is a big challenge to achieve the enantioselective recognition with both high enantioselectivity and

Chiral recognition of carbon nanoforms

Organic & Biomolecular Chemistry, 2012
The selective recognition of chiral carbon nanoforms poses a fundamental challenge. New design principles must be devised to construct hosts capable of enantiodiscrimination between species in which chirality does not arise from asymmetric carbon atoms.

Electronic Dissymmetry in Chiral Recognition

Journal of the American Chemical Society, 2005
The pi-bonding of the beta-diketonate ligands in C2-symmetric (dike)2TiX2 complexes engenders a significant electronic dissymmetry, with the LUMO of the complex resembling a "tipped" dz2 orbital whose tilt with respect to the plane containing the metal and the two X groups is determined by the configuration at titanium.

Increasing chiral recognition in acetal formation

Chirality, 2008
AbstractThe design of substituted lactols is described, which in their reaction with racemic alkyl aryl carbinols react preferentially with one of the enantiomers exhibiting selectivities up to 14:1. Chirality, 2009. © 2008 Wiley‐Liss, Inc.

Chirality and Chiral Recognition

2009
This review summarizes the literature survey on chiral recognition from a theoretical view point. Nevertheless, experimental results in the gas phase are reported when they are relevant for the theoretical calculations. The review is divided into the following sections: general considerations; experiment vs.

Carborane-Cluster-Wrapped Copper Cluster with Cyclodextrin-like Cavities for Chiral Recognition.

Journal of the American Chemical Society
Chiral atomically precise metal clusters, known for their remarkable chiroptical properties, hold great potential for applications in chirality recognition.
