18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

Novel Application of UHPLC–MS, HRMS, and 2D‐NMR for Structural Elucidation of Eletriptan Hydrobromide and Its Novel Degradation Products

Biomedical Chromatography, Volume 40, Issue 2, February 2026.
ABSTRACT A stability‐indicating UHPLC–MS method was developed to investigate the stress degradation behavior of eletriptan hydrobromide under ICH‐recommended acidic, alkaline, neutral, oxidative, thermal, and photolytic conditions. Significant degradation was observed only under acidic and oxidative stress.

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...

Redox-neutral α-functionalization of pyrrolidines: facile access to α-aryl-substituted pyrrolidines

RSC Advances
Using a quinone monoacetal as the oxidant and DABCO as the base, we report the one-step synthesis of α-aryl-substituted pyrrolidines from pyrrolidine. The reaction of pyrrolidine and quinone monoacetal in 2,2,2-trifluoroethanol afforded octahydro-dipyrroloquinoline in high yield.
