Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Updated EAACI Statement on Drug Hypersensitivity Skin Testing: Methodology and Non‐Irritative Concentrations

open access: yesAllergy, EarlyView.
ABSTRACT These updated EAACI guidelines aim to standardize skin testing methodologies for both immediate and non‐immediate drug hypersensitivity reactions. For immediate reactions, the optimal testing window is 4–6 weeks post‐reaction; whereas beyond 6 months, false‐negative results increase.

Nomenclature on Immune‐Mediated Drug Reactions: An EAACI Position Paper

open access: yesAllergy, EarlyView.
ABSTRACT Over the past several decades, there have been significant advances in our understanding of both immunological and pharmacological mechanisms of adverse drug reactions (ADRs). Immune‐mediated drug reactions (IMDRs) represent a small proportion of ADRs and are caused by a pathological activation of the immune system or inflammatory pathways ...
