Chemistry – A European Journal, EarlyView.Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Counterfeit Drugs: The Good, the Bad, and the Ugly [PDF]
, 2006 When I chose the title, Counterfeit Drugs: The Good, the Bad and the Ugly, some of my colleagues at this symposium blanched. They understood counterfeit drugs as Bad and Ugly, but resisted categorizing any counterfeit drug as Good.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids
Chemistry – A European Journal, EarlyView.This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Drug Testing and Analysis, EarlyView.Micro‐QuEChERS sample preparation coupled to LC‐QQQ‐MS enabled sensitive quantification of nitazene analogs in 100 μL of plasma. The validated method provided low detection limits and was successfully applied to an authentic intoxication case involving N‐pyrrolidino protonitazene, supporting clinical and forensic toxicology workflows.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles
European Journal of Organic Chemistry, EarlyView.Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]
