Si(OTeF5)4 – A Strong, Homoleptic Pentafluoroorthotellurate‐Based Lewis Superacidic Silane

open access: yesChemistry – A European Journal, EarlyView.
The homoleptic pentafluoroorthotellurate‐based silane Si(OTeF5)4 was synthesized and fully characterized via spectroscopic techniques. The Lewis superacidic properties were investigated theoretically as well as experimentally and its utilization as a Lewis acid is demonstrated by the reaction with nitrogen bases.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

open access: yesChemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Trends and Future Directions in Organic Chemistry for Drug Discovery

open access: yesChemistry – A European Journal, EarlyView.
Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.

The comparison of sodium fluoride 0,05% and iodized salt 2% solution in reducing of Candida sp [PDF]

open access: yes, 2009
Background: Acrylic denture base users were suggested to use mouthwash daily to reduce plaque formation. Sodium fluoride 0,05% and iodized salt 2% solution are two mouthwashes which can kill Candida sp., most common microorganism in acrylic denture ...

Cyclic Disulfide Sorting Influenced by Subtle Steric and Electronic Effects

open access: yesChemistry – A European Journal, EarlyView.
The self‐assembly of two unsymmetrical dithiols to form cyclic disulfides are examined with an eye to the longitudinal equilibration behavior and directing agent effects on product distributions. Cyclic disulfide formation occurs in under 2 min, with full equilibration requiring up to 1 week.
