Electrochemical Synthesis of Isoxazoles and Isoxazolines via Anodic Oxidation of Oximes
Isoxazol(in)es are widely featured structural motifs in natural products, agrochemicals, and pharmaceuticals. The first intermolecular approach for a direct electrochemical synthesis from readily available aldoximes is reported.

Amides, anhydrides, esters, and thioesters of 2H-azirine-2-carboxylic acids were prepared by a rapid procedure at room temperature involving FeCl2-catalyzed isomerization of 5-chloroisoxazoles to 2H-azirine-2-carbonyl chlorides, followed by reaction with

Development of the novel isoxazolo[3,4-d]pyridazinone scaffold, which positively modulates the metabotropic glutamate receptor subtypes 2 and 4 [PDF]
The seven transmembrane (7TM) superfamily, also known as G-protein coupled receptors (GPCR), are one of the largest superfamilies in the human genome.

The first photocycloadditions of aromatic and aliphatic aldehydes to methylated isoxazoles are reported. The reactions lead solely to the exo-adducts with high regio- and diastereoselectivities. Ring methylation of the isoxazole substrates is crucial for

Conjugated azapolyenes (azabuta-1,3-dienes, aza-/diaza-/oxaza-/oxadiazahexa-1,3,5-trienes) are highly reactive in electrocyclization reactions, which makes them convenient precursors for the synthesis of a wide range of four-, five-, and six-membered ...

Gold-catalysed [4+3]- and [4+2]-annulations of 3-substituted 3-en-1-ynamides with isoxazoles were achieved with Au(i) and Au(i)/Zn(ii) catalysts respectively.

Target Agnostic Photoaffinity Labelling by Sulfonylhydrazones. [PDF]
Sulfonyl hydrazones were identified as new photo‐crosslinkers exploiting their base catalyzed low‐energy photoactivation that leads to reactive carbenes. The amino acid promiscuity, their usefulness in proteomics application and the range of labelled targets including enzymes, a PPI target and a transcription factor suggests that sulfonyl hydrazones ...

Nitroimidazoles XIII. Synthesis of Substituted (1-Methyl-5-Nitro-2-Imidazolyl) Isoxazoles [PDF]
The beta0diketone derivatives of nitroimidazole were synthesized from the reaction of magnesium salt of beta-ketoaccids 3 with imidazolide 4. The raction of beta-diketones with hydroxylamine hydrochloride afforded either the isoxazoles or the 5-hydroxyl ...

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy
ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...
