Multidimensional Engineering Enabling Rate‐Matched C−N Coupling for Efficient Organonitrogen Electrosynthesis

open access: yesEcoEnergy, EarlyView.
This review introduces rate matching as a unifying design principle for efficient electrochemical C−N coupling and highlights multidimensional engineering of catalysts, interfaces, and reactors to synchronize the generation of carbon‐ and nitrogen‐containing intermediates, balance their surface coverages, maximize C−N bond formation, and enable ...

Iterative Assembly of Nitrile Oxides and Ynamides: Synthesis of Isoxazoles and Pyrroles

open access: yes, 2019
Described is an iterative assembly of nitrile oxides and ynamides for the synthesis of isoxazoles and pyrroles. The nitrile oxides could undergo Cu­(I)-free cyclization with terminal ynamides for accessing isoxazoles, which could engage in another ...

5-(Benzoyloxymethyl)isoxazole-3-carboxylic Acid Ethyl Ester

open access: yesMolbank
We describe here the palladium hydrogenation of ethyl 5-(benzoyloxymethyl)isoxazole-3-carboxylate. The presence of two reducible sites in the molecule, namely the benzylic-like position and the isoxazole N–O bond, creates a possible competition.

Risk of hostility and aggression with perampanel monotherapy versus combination therapy in pediatric epilepsy: A Japanese post‐marketing database study using a nested case–control design

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective To compare the incidence of hostility‐ and aggression‐related adverse events in children with focal‐onset seizures (FOS), with or without focal to bilateral tonic–clonic seizures (FBTCS), receiving perampanel as monotherapy or in combination with other antiseizure medications (ASMs).

Do preclinical seizure models predict success or failure in anti‐seizure drug development? A retrospective analysis of 89 compounds with divergent clinical outcomes for epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Anti‐seizure medication (ASM) discovery remains a major challenge despite over 30 commercially available options. One persistent obstacle for any promising candidate compound to successfully move from preclinical study to clinical approval has been the ambiguity in preclinical model selection.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
