A MassQL‐Based Framework for Rule‐Guided MS/MS Class‐Level Retrieval and Analog Discovery of Cannabinoids

Rapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Cannabinoids comprise a chemically diverse group of meroterpenoids whose extensive isomerism, variable side‐chain length, and frequent oxidative or rearranged derivatives lead to strongly overlapping yet characteristic MS/MS fragmentation patterns. In untargeted LC–MS/MS datasets, this combination of structural diversity and spectral

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 ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, Volume 29, Issue 32, 24 August 2026.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, Volume 47, Issue 16, Page 14313-14338, 20 August 2026.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.
