Photochemisch erzeugte Oxetane als Schlüssel zur endergonen Cyclopropansynthese

Angewandte Chemie, Volume 138, Issue 35, 24 August 2026.
Eine neuartige Oxetan‐zu‐Cyclopropan‐Umlagerung eröffnet einen atomökonomischen Zugang zu dicht funktionalisierten Cyclopropanen aus Furanen und photochemisch aktivierten Aldehyden. Die erhaltenen Strukturen erschließen komplexe bioaktive Motive und fungieren als vielseitige Plattform für die asymmetrische Cyclopropansynthese.

Photogenerated Oxetanes as a Gateway to Uphill Cyclopropanation

Angewandte Chemie International Edition, Volume 65, Issue 35, 24 August 2026.
An atom‐economical route to densely functionalized cyclopropanes from furans and photochemically activated aldehydes is enabled by a unique oxetane‐to‐cyclopropane rearrangement. These cyclopropanes can be used to access complex bioactive scaffolds and serve as a platform for asymmetric cyclopropane synthesis.

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes

Chemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

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

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
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 ...
