Looking for the Origin of Allosteric Cooperativity in Metallopolymers

The basic concept of allosteric cooperativity used in biology, chemistry and physics states that any change in the intermolecular host-guest interactions operating in multisite receptors can be assigned to intersite interactions. Using lanthanide metals as guests and linear multi-tridentate linear oligomers of variable lengths and geometries as hosts, this work shows that the quantitative modeling of metal loadings requires the consideration of a novel phenomenon originating from solvation processes. It stepwise modulates the intrinsic affinity of each isolated site in multisite receptors, and this without resorting to allosteric cooperativity. An easy-to-handle additive model predicts a negative power law dependence of the intrinsic affinity on the length of the linear metallopolymer. Applied to lanthanidopolymers, the latter common analysis overestimates cooperativity factors by more than two orders of magnitude.

Designing Structural Motifs for Clickamers: Exploiting the 1,2,3-Triazole Moiety to Generate Conformationally Restricted Molecular Architectures

Noncovalent interactions, especially hydrogen-bonding interactions as well as electrostatic forces, confined within one macromolecule are the key to designing foldamers that adopt well-defined conformations in solution. In the context of significant recent activities in the area of triazole-connected foldamers, so-called clickamers, we present a fundamental study that compares various model compounds that bear adjacent N-, O-, or F-heteroatom substituents. The interplay of attractive and repulsive interactions leads to rotational constraints around the single bonds attached to both the 1- and 4-positions of the 1,2,3-triazole moiety and should therefore be able to induce well-defined conformational preferences in higher oligomers and polymers, that is, foldamers. Various compounds were synthesized and characterized with regard to their preferred conformations in all three aggregation statesa-that is, in the gas phase, in solution as well as in the solid statea-by employing DFT calculations, NMR spectroscopic experiments, and X-ray crystallography, respectively. On the basis of the thus-obtained general understanding of the conformational behavior of the individual connection motifs, heterostructures were prepared from different motifs without affecting their distinct folding characteristics. Therefore, this work provides a kind of foldamer construction kit, which should enable the design of various clickamers with specific shape and incorporated functionality. A foldamer construction kit: Various heterostructures "clicked" together by structure-directing triazole moieties were investigated with regard to their conformational behavior. Different heteroatoms (X; see graphic) can be used to bias the conformation around the N(1)- and C(4)-connecting single bonds of the triazoles based on tunable noncovalent interactions.

An expedient synthesis of CPS124 (1) is described using the diastereoselective reaction of the in situ generated dichlorophosphite 6 with L-carnitine tetrafluoroborate salt 7 under kinetic control as the key step. Alkylations of resorcinol 2 and its benzoate 13 are discussed. The use of α-cellulose as a support for solids that are difficult to filter or low melting is presented.

Selective etherification of polyhydroxybenzenes using PEG 200 as solvent or cosolvent

The monoalkylation of hydroquinone is performed using PEG 200 as a solvent or a cosolvent.The effect on the selectivity of the base strength, the temperature, and the percentage of cosolvent are discussed.The substituted phenols were found to behave differently upon etherification.When a carboxylic function is present in the ring, the hydroxybenzoic acids were selectively etherified using pure PEG and sodium hydroxyde as a base.Substituted diphenols were selectively etherified using a mixture of PEG and dioxan and potassium hydrogencarbonate as a base.Keywords - etherification / selectivity / polyhydroxybenzenes / polyethylene glycol
