Resumen
The first step in the photochemical decarboxylation of isoxazolones is the formation of the triplet state of the isoxazolone. We present evidence for the first time from flash laser photolysis of the lifetime of such species, and examples of their capture by solvent and by intramolecular cycloaddition.

Resumen
Several approaches to the synthesis of derivatives of the antifungal antibiotic TAN-950A, which is also an agonist of glutamate at hippocampal neurons, are reported. Additions of isoxazolon-4-yl anions to methyleneoxazolidinones were not useful because addition occurred predominantly through N-2. Similarly addition of the isoxazolon-4-yl radicals to model Michael acceptors occurred predominantly through N-2. Racemic analogues of TAN-950A were prepared by reaction of isoxazolone Mannich bases with acetylaminomalonate or addition of β-ketoester anions to dehydroalanines. The best approach to ena

Resumen
This study examined the effect influence of various factors on the extraction of Pd(II) to develop a new liquid-liquid extraction mechanism for the selective separation of palladium(II) from its acidic chloride solutions using 4-aroyl-3-phenyl-5-isoxazolones (HA), such as 3-phenyl-4-(4-fluorobenzoyl)-5- isoxazolone (HFBPI), 3-phenyl-4-benzoyl-5-isoxazolone (HPBI) and 3-phenyl-4- (4-toluoyl)-5-isoxazolone (HTPI). The extraction strength of Pd(II) with HA were in the following order: HFBPI > HPBI > HTPI, which is opposite to that observed with their pKavalues. HPBI was used to separate Pd(

Resumen
The development of effective, nontoxic antifungal agents is one of the most important challenges for medicinal chemistry. A series of isoxazolo [3,4-b]pyridine-3(1H)-one derivatives previously synthesized in our laboratory demonstrated promising antifungal properties. The main goal of this study was to investigate their retention behavior in a human serum proteins-high-performance liquid chromatography (HSA-HPLC) system and explore the molecular mechanism of HSA-isoxazolone interactions using a quantitative structure–retention relationship (QSRR) approach. In order to realize this goal, multip

Resumen
The reaction of 1,4-dichlorophthalazine and 2,3-dichloroquinoxaline with some isoxazolones gave their mono- and bis-isoxazolinyl derivatives. The base-catalyzed rearrangement of these derivatives afforded the corresponding tri- and tetracyclic heterocycles.
