Crystal structure and Hirshfeld surface analysis of 2-azido-N-(4-fluorophenyl)acetamide

Acta Crystallographica Section E: Crystallographic Communications, 2022
The asymmetric unit of the title compound, C8H7FN4O, consists of two independent molecules differing in the orientation of the azido group. Each molecule forms N—H...O hydrogen-bonded chains along along the c-axis direction with its symmetry-related ...

Crystal structure and Hirshfeld surface analysis of N-(4-nitrophenyl)-2-(piperidin-1-yl)acetamide (lidocaine analogue)

Acta Crystallographica Section E: Crystallographic Communications
In the title molecule, C13H17N3O3, the substituents on the phenyl ring are rotated slightly out of the mean plane of the ring but the piperidine moiety is nearly perpendicular to that plane. In the crystal, C—H...O hydrogen bonds form chains of molecules

Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

Angewandte Chemie, EarlyView.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

A High‐Voltage Membrane‐Free Li–Organic Hybrid Flow Battery Using Eutectic Lithium Chemistry

Angewandte Chemie, EarlyView.
A high‐voltage (3.6 V) membrane‐free Li–organic hybrid flow battery is enabled by a deep‐eutectic lithium electrolyte composed of trifluoroacetamide (TFAD) and LiPF6, paired with a dichloromethane (DCM) catholyte containing phenothiazine (PTZ). The TFAD/LiPF6 eutectic provides fast Li+ transport and stable Li‐metal cycling, while the immiscible TFAD ...

Induction and Stabilization of Peptide Alpha‐Helices on Silica Nanoparticles

Angewandte Chemie, EarlyView.
Covalent docking turns silica nanoparticles (SNPs) into α‐helix‐stabilizing surfaces. Dynamic imine formation allows peptides with lysine residues aligned on one helical face to adapt to the surface before reduction locks the structure in place, while preserving the opposite face for functional recognition.
