The Chemistry and Biology of the Tetrodotoxin Natural Product Family
Angewandte Chemie International Edition, Accepted Article.Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Induced Chirality and Vibrational Optical Activity in an Ionic‐Liquid Anion
Angewandte Chemie International Edition, EarlyView.Chirality can be induced in an ionic liquid anion. Normally, the enantiomeric conformers are equally populated, and no optical activity is observed. However, if a chiral probe molecule (e.g., propylene oxide) is added, a non‐symmetric redistribution of the conformers occurs, chirally imprinting the ionic liquid.

Is Phenylnitrene a Missing Link in the Formation of Polycyclic Aromatic Nitrogen Heterocycles?
Angewandte Chemie International Edition, EarlyView.A new formation pathway for polycyclic aromatic nitrogen heterocycles (PANHs) has been found. The reaction of phenylnitrene and the propargyl radical leads to quinoline, proving that nitrenes are suitable precursors for nitrogen incorporation mechanisms.
