This perspective highlights radical‐mediated 1,2‐boryl migration as a thermodynamically driven radical translocation strategy that enables the construction of diverse functionalized organoboronates, the transposition editing of organic molecules, and the synthesis of C3 alternating copolymers.

Five Decades of Dispute: A Triptych. E. J. Corey
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
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.

ABSTRACT Long‐term exposure to low‐dose food contact materials (FCMs) has raised concerns regarding developmental toxicity. In the present study, we prioritized FCMs with potential developmental toxicity using a weight‐of‐evidence computational model, which predicted 127 chemicals to be of high concern.

This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome
Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

A tandem fluorescent mCherry–EGFP–LC3 reporter enables live‐cell visualisation of autophagy–lysosome dynamics in naked mole‐rat skin fibroblasts. Chloroquine‐induced lysosomal stress promotes accumulation of neutral LC3‐positive compartments and triggers pronounced LC3‐associated vacuolation.

ABSTRACT Objectives To evaluate the effect of reduced dentin etching time on the clinical performance of two universal adhesive systems in noncarious cervical lesions (NCCLs). Methods A total of 144 NCCLs restorations were randomly placed in 36 participants according to four experimental groups: SUP5 (Scotchbond Universal Plus adhesive [pH ≈2.5–2.7 ...
