Summary
Two novel cyclic peptide cryptands with thiourea frameworks were synthesized. These neutral receptors demonstrate high affinity binding for acetate ions, with one showing notable selectivity.
Area of Science:
- Supramolecular Chemistry
- Organic Synthesis
Background:
- Anion recognition is crucial in biological and chemical processes.
- Developing synthetic receptors for specific anions remains a challenge.
Purpose of the Study:
- To synthesize novel cyclic peptide derived cryptands.
- To investigate their potential as neutral anion receptors.
Main Methods:
- Synthesis of two cyclic peptide derived cryptands.
- Incorporation of thiourea moieties into the cryptand framework.
- Anion binding studies, focusing on acetate ions.
Main Results:
- Successful synthesis of two cyclic peptide derived cryptands.
- Demonstrated high affinity binding of acetate ions by both receptors.
- One cryptand exhibited good selectivity for acetate ions.
Conclusions:
- Cyclic peptide derived cryptands with thiourea groups are effective neutral anion receptors.
- These compounds show promise for selective acetate recognition.

Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

Preparation of Acid Anhydrides
One of the methods for preparing symmetrical or unsymmetrical acid anhydrides involves the treatment of acid chlorides with the sodium salt of carboxylic acids. The reaction proceeds via a nucleophilic acyl substitution.
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...

Preparation of Amides
Amides are synthesized by treating carboxylic acids with amines in the presence of dehydrating agents like dicyclohexylcarbodiimide (DCC).
The DCC-promoted synthesis of amides begins with the protonation of DCC by carboxylic acid. The protonation makes it a better acceptor. Next, the addition of carboxylate to the protonated carbodiimide gives a reactive acylating agent.
Subsequently, the amine acts as a nucleophile that attacks the acylating agent to form a tetrahedral intermediate. In the...
