Multiple Isomers and Protonation Sites of the Phenylalanine/Serine Dimer

Our investigation of the phenylalanine/serine (Phe/Ser) protonated dimer suggests that the intermolecular interaction between the two amino acids is more complex than could have been anticipated from previous studies of similar systems. Isomer-specific inf ...

Tuning and predicting biological affinity: aryl nitriles as cysteine protease inhibitors

Pablo Rivera Fuentes, Matthias Rottmann, Jose Enrico Quijano Quinsaat, Céline Freymond

A series of aryl nitrile-based ligands were prepd. to investigate the effect of their electrophilicity on the affinity against the cysteine proteases rhodesain and human cathepsin L. D. functional theory calcns. provided relative reactivities of the nitril ...

Functional, Hyperbranched Polyesters Via Baylis-Hillman Polymerization

Harm-Anton Klok, Frederik Roman Wurm, Sanhao Ji

Hyperbranched polyesters are among the most common hyperbranched polymers. One of the interesting features of hyperbranched polyesters is that they contain unreacted hydroxyl and carboxylic acid groups at the linear and terminal structural units, which can ...

Engineering of highly efficient tetrahydroquinoline sensitizers for dye-sensitized solar cells

Ulf Anders Hagfeldt, Yan Hao

Four novel tetrahydroquinoline dyes by inserting isophorone and/or thiophene moieties as π bridge between the electron donating unit of substituted tetrahydroquinoline and the electron withdrawing unit of cyano carboxylic acid have been synthesized and suc ...

Synthesis of Side-Chain Functional Polyesters via Baylis-Hillman Polymerization

Harm-Anton Klok, Sanhao Ji

Strategies that allow access to side-chain functional polyesters are valuable as they would enable to engineer the properties of these hydrolytically degradable materials. This contribution explores the feasibility of a novel approach toward side-chain fun ...

Kinetic Control in the Chiral Recognition of Three-Bladed Propellers

Natalie Renuka Banerji, Jérôme Lacour

The ion pair of the stereolabile C3-symmetric, i+o proton complex [1⋅H]+ of diaza-macropentacycle 1 and the configurationally stable Δ-TRISPHAT ([Δ-3]−) anion exists in the form of two diastereomers, namely, [Δ-(1⋅H)][Δ-3] and [Λ-(1⋅H)][Δ-3], the ratio of ...

Head-To-Tail and Heteroleptic Pentanuclear Circular Helicates

Everybody form a circle: Careful design of ligand strands and their reaction with Cu2+ ions leads to the formation of the title helicates. Incorporation of differing numbers of N-donor units within a ligand strand containing a phenyl spacer results in a pe ...

Tetraalkylammonium Salts of Weakly Coordinating Aluminates: Ionic Liquids, Materials for Electrochemical Applications and Useful Compounds for Anion Investigation

Michael Graetzel, Mingkui Wang, Ines Raabe

In this study, we investigated the tetraalkylammonium salts of the weakly coordinating fluorinated alkoxyaluminates pftb (Al(O(C(CF3)(3))(4)) hfip (Al(OC(H)-(CF3)(2))(4)) and hftb (Al(OC(CH3)(-) (CF3)(2))(4)) in order to obtai ...

LABORATORY DETECTION OF HOCN AND TENTATIVE IDENTIFICATION IN Sgr B2

Sandra Bruenken

The rotational spectrum of cyanic acid, HOCN, has been detected in the centimeter-wave band in a molecular beam by Fourier transform microwave spectroscopy and in the millimeter-wave band by conventional spectroscopy in a low-pressure laboratory discharge. ...
