Chirality sensing of choline derivatives by a triple anion helicate cage through induced circular dichroism

03-Jul-2018 | Wei Zuo; Zhe Huang; Yanxia Zhao; Wenhua Xu; Zhihua Liu; Xiao-Juan Yang; Chuandong Jia; Biao Wu, Chemical Communication, 2018

Chirality sensing of choline derivatives is achieved by a self-assembled, racemic triple anion helicate cage which exhibits induced circular dichroism (ICD) upon encapsulation of a chiral guest. The host–guest interactions were illustrated by NMR, crystal structure, CD and DFT calculations. The ...

Stereocontrolled Self-Assembly and Photochromic Transformation of Lanthanide Supramolecular Helicates

26-Jun-2018 | Li-Xuan Cai; Liang-Liang Yan; Shao-Chuan Li; Lipeng Zhou; Qing-Fu Sun, Dalton Transactions, 2018

Stereocontrolled self-assembly of dinuclear triple-stranded Europium helicate (Eu2L3) based on DTE-functionalized ligands has been achieved via the chiral-induction strategy. The point-chirality of the ligands was transferred to give either Δ or Λ metal-centers and hence leads to an overall P or ...

Separation of enantiomers by their enantiospecific interaction with achiral magnetic substrates

22-Jun-2018 | Koyel Banerjee-Ghosh; Oren Ben Dor; Francesco Tassinari; Eyal Capua; Shira Yochelis; Amir Capua; See-Hun Yang; Stuar ..., Science , 2018

It is commonly assumed that recognition and discrimination of chirality, both in nature and in artificial systems, depend solely on spatial effects. However, recent studies have suggested that charge redistribution in chiral molecules manifests an enantiospecific preference in electron spin ...

Dearomative [2,3] sigmatropic rearrangement of ammonium ylides followed by 1,4-elimination to form [small alpha]-(ortho-vinylphenyl)amino acid esters

20-Jun-2018 | Eiji Tayama; Sho Sotome, Organic & Biomolecular Chemistry, 2018

A base-induced dearomative [2,3] sigmatropic rearrangement of amino acid ester-derived ammonium salts followed by 1,4-elimination produced α-(ortho-vinylphenyl)amino acid esters. The reaction of azetidine-2-carboxylic acid-derived ammonium salt (1S,2S,1’R)-3b proceeded with a perfect N-to-C ...

Intermediate length-scale chirality related to the vibrational circular dichroism intensity enhancement upon fibril formation in a gelation process

01-Jun-2018 | Hajime Torii; Hisako Sato, Physical Chemistry Chemical Physics, 2018

Chiro-optical spectroscopic methods, such as vibrational circular dichroism (VCD) spectroscopy, are regarded as useful measures that provide us information on the structural properties of chiral species, but for correct interpretation of the measured spectra, appropriate modeling that can be ...
