Δ2-isoxazolines from arylcyclopropanes: III. Phenylcyclopropanes substituted in three-membered ring in reaction with nitrosyl chloride activated with oxides of sulfur(IV, VI)
摘要:
The reaction of phenylcyclopropanes substituted in the three-membered ring with nitrosyl chloride activated with sulfur(IV, VI) oxides provided in good yield substituted 5-phenylisoxazolines as a mixture of structural isomers.

building blocks for covalently binding ligands. Six reactive groups with modulated electrophilicity were combined with 11 nonreactive moieties, resulting in a small combinatoriallibrary of 72 fragment-like compounds. These compounds were screened against a group of 11 enzyme targets to assess their selectivity and their potential for promiscuous binding to proteins. The assay results showed a considerably

A Cu(I)-catalysed Sonogashira-type cross coupling reaction with aliphatic or aromatic bromoisoxazolines or N-alkoxyimidoyl bromides and alkynes is reported. The protocol we developed employs catalytic amount of copper(I), non-toxic ligand bathophenanthroline and is tolerant to a wide range of functional groups and is therefore particulary adapted in the context of drug discovery.

Natural and synthetic electrophilic compounds have been shown to activate the antioxidant protective Nrf2 (nuclear factor erythroid 2‐related factor 2)/heme oxygenase‐1 (HO‐1) axis in cells and tissues. Here, we tested the ability of different isoxazoline‐based electrophiles to up‐regulate Nrf2/HO‐1. The potency of activation is dependent on the leaving group at the 3‐position of the isoxazoline nucleus

Several haloisoxazoline analogues of α-amino-3-chloro-4,5-dihydro-5-isoxazole acetic acid (1, AT-125) were prepared by means of 1,3-dipolar cycloaddition methodology. The chemistry of these compounds is discussed, and a possible biological mode of action of AT-125 presented.
