Shielded alkyl-functionalised rotaxane host cavities for improved anion recognition

The synthesis and anion recognition properties of four novel [2]rotaxane host architectures containing additional alkyl functionality integrated within macrocyclic and axle components to shield the binding cavity from the solvent are described. The rotaxane species containing a tetra(methyl)-functionalised macrocycle component is found to be a weaker anion complexant than the equivalent unfunctionalised receptor, which is likely due to steric hindrance restricting the anion's access to the interlocked cavity. Rotaxane molecules containing tetra(methyl)-functionalised axle components are also investigated, and the additional alkyl functionality serves to enhance anion binding affinity and selectivity when incorporated within the axle's flexible ethylene linkages. Moreover, the equivalent unfunctionalised rotaxane displays a rare preference for oxoanions over chloride guest species.

Self-assembly of a pyridyl derivative and its silver complex: Formation of a liquid crystalline phase and organogels

Self-assembling behavior of N,N′-didodecyl-3,5-pyridinedicarboxamide and its silver complex has been studied. They act as gelators in solution and gelate a variety of organic solvents. Though the silver complex exhibits lower gelation abilities for halogenated and aromatic solvents, long-term stability is achieved for ethanol and acetone gels. Moreover, the silver complex exhibits a smectic A phase on cooling while a single component of N,N′-didodecyl-3-5- pyridinedicarboxamide exhibits no mesomorphic behavior. The XRD pattern for the complex shows that the layer spacing of the SA phase is 37 A.

Perfluorinated Pyridinium and Imidazolium ionic liquids

Ionic liquids with perfluorinated side chains were prepared as hybrid materials for surface impregnation. For the cationic part, methyl and ethyl pyridinium as well as imidazolium scaffolds were used. The anions investigated were hydroxide, acetate, trifluoroacetate, triflate, triflimide, chloride, bromide, iodide, hydrogensulfate, and perfluorododecanoate. A key feature of this investigation is the finding that the use of relatively short perfluorohexyl residues as the fluorinated part of the salts is beneficial for the target compounds compared with established products, because of their lower bioaccumulativity. One compound yielded single crystals that were suitable for X-ray structure analysis, revealing a layered structure with relatively well-resolved, hard ionic domains alternating with disordered, soft perfluorinated layers. The wettability of all 30 materials was investigated by water contact angle measurements of a thin film on a glass surface. In two cases, promising contact angles (130° and 140°) were observed, indicating that the products might be suitable candidates for the impregnation of surfaces.

Recognition by a solubilized receptor: Hydrogen bonding, solvophobic interactions, and solvent engineering inside micelles

This paper shows how a hydrophobic porphyrin-based receptor capable of multipoint recognition in organic solvents can be solubilized directly in water by incorporation inside micelles. Binding of ligands from the aqueous phase is analyzed in sodium dodecylsulphate (SDS) micelles using a simple model in which ligands first partition into the micelle and are then complexed by the receptor. Subtraction of ligand-micelle partitioning terms from observed binding energies gives energies for bimolecular association inside SDS micelles, which range from +1 to -22 kJ/mol (equilibrium constants from 0.7 to 7900 M-1). Comparison of two receptors binding the same set of ligands in SDS and organic solvents then provides insight into the roles of ligand and receptor solvation in micellar recognition. Binding inside SDS micelles is found to be energetically similar to binding in methanol, in that hydrogen bonding in the SDS pseudophase is reduced relative to CH2Cl2, and association of ligands capable of nonpolar contacts with the receptor is enhanced. Micellar recognition is most effective when both hydrogen bonding and solvophobic forces act together, leading to increased chiral discrimination of hydrophobic amino acid derivatives. It is finally shown how receptor solvation inside micelles can be tuned by the addition of organic cosolvents, reducing solvophobic association and restoring some of the hydrogen bonding energy.

Synthesis and antimicrobial activity of some linear dipeptide pyridine and macrocyclic pentaazapyridine candidates

A series of tetracarboxamide and macrocyclic tripeptides have been prepared starting from 3,5-bis[N-(1-hydrazinyl-1-oxo-3-phenylpropan-2-yl)]pyridinecarboxamide 4 as starting material, which was synthesized from dinicotinic acid 1. Treatment of 4 with 1,4-diaminobutane, 1,6-diaminohexane, or cycloalkanone derivatives gave the corresponding macrocyclic tetracarboxamides (5a, b) and cycloalkyl hydrazone derivatives (6a-c), respectively. Additionally, the reaction of 4 with acetophenone or acetylpyridine derivatives gave the corresponding Schiff base derivatives 7a-e and 8a-c, respectively. Also, carboxylic acid hydrazide 4 was treated with acid anhydrides in glacial acetic acid to afford the corresponding diimide tetracarboxamide derivatives 9a, b, 10, and 11, respectively. The structures of newly synthesized compounds are established by physical and spectral data evidences. Some of the synthesized compounds were screened as antimicrobial agents.

A predictive model for additions to: N -alkyl pyridiniums

Disclosed in this communication is a thorough study on the dearomative addition of organomagnesium nucleophiles to N-alkyl pyridinium electrophiles. The regiochemical outcomes have observable and predictable trends associated with the substituent patterns on the pyridinium electrophile. Often, the substituent effects can be either additive, giving high selectivities, or ablative, giving competing outcomes. Additionally, the nature of the organometallic nucleophilic component was also investigated for its role in the regioselective outcome. The effects of either reactive component are important to both the overall reactivity and site of nucleophilic addition. The utility of these observed trends is demonstrated in a concise, dearomative synthesis of a tricyclic compound shown to have insecticidal activity. This journal is
