The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

Chemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

Chemistry – A European Journal, EarlyView.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Stafib‐2‐CR: an Improved Nanomolar and Selective Inhibitor of the Transcription Factor STAT5b Developed by Conformational Restriction of Stafib‐2

Chemistry – A European Journal, EarlyView.
Conformational restriction strategies to increase the activity and selectivity of the STAT5b inhibitor Stafib‐2 are presented. The best conformationally restricted inhibitor Stafib‐2‐CR has threefold higher activity against STAT5b than Stafib‐2. A cell‐permeable prodrug of Stafib‐2‐CR inhibits phosphorylation of STAT5b in cultured human leukemia cells ...

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

Chemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...
