[Aromatic Foldamers Recognizing Saccharides to Form Chiral Helices]
1Graduate School of Pharmaceutical Sciences, University of Toyama.
Summary
New foldamers with pyridine and phenol units show enhanced saccharide recognition and stable helical structures. These meta-arylene ethynylene compounds enable efficient solid-liquid extraction through strong binding interactions.
Area of Science:
- Organic Chemistry
- Supramolecular Chemistry
- Materials Science
Background:
- Foldamers are synthetic oligomers mimicking protein secondary structures.
- Arylene ethynylene foldamers offer tunable properties for molecular recognition.
- Hydrogen bonding plays a crucial role in dictating foldamer conformation and function.
Purpose of the Study:
- To develop novel meta-arylene ethynylene foldamers incorporating pyridine and phenol units.
- To investigate the impact of phenol units on saccharide recognition and binding affinity.
- To explore methods for stabilizing foldamer helical structures and controlling helical sense.
Main Methods:
- Synthesis of pyridine and phenol-containing meta-arylene ethynylene foldamers.
- Evaluation of saccharide binding and recognition capabilities using spectroscopic methods.
- Employing alkene metathesis for hydrocarbon stapling to stabilize helical structures.
- Investigating intramolecular hydrogen bonding for spontaneous helix formation.
Main Results:
- Pyridine-acetylene-phenol foldamers exhibited enhanced saccharide recognition compared to those lacking phenol units.
- Strong binding interactions facilitated efficient solid-liquid extraction of saccharides.
- Hydrocarbon stapling via alkene metathesis effectively stabilized the foldamer helical structures.
- Phenol-acetylene oligomers spontaneously formed helical structures driven by intramolecular hydrogen bonding.
- Chiral amines were used to bias the helical sense of the foldamers.
Conclusions:
- The incorporation of phenol units significantly improves saccharide recognition in meta-arylene ethynylene foldamers.
- These foldamers demonstrate potential applications in separation technologies like solid-liquid extraction.
- Alkene metathesis and intramolecular hydrogen bonding are effective strategies for stabilizing and controlling foldamer helicity.

02:25Chirality
29.3K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

17.0K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

01:14Nucleophilic Aromatic Substitution of Aryldiazonium Salts: Aromatic SN1
2.7K
Treating arylamines with nitrous acid gives aryldiazonium salts that are effective substrates in nucleophilic aromatic substitution reactions. The diazonio group in these salts can be easily displaced by different nucleophiles, yielding a wide variety of substituted benzenes. The leaving group departs as nitrogen gas, and this easy elimination is the driving force for the substitution reaction.
In the Sandmeyer reaction, for example, the diazonio group is replaced by a chloro, bromo,...

02:25Molecules with Multiple Chiral Centers
14.9K
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

02:30Chirality at Nitrogen, Phosphorus, and Sulfur
6.9K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

01:25Aromatic Compounds: Overview
13.7K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.
