Hypoxic‐ischemic encephalopathy (HIE) is a neurologic condition that is caused by insufficient oxygen and blood flow to a newborn infant’s brain. Although therapeutic hypothermia can reduce the degree of brain injury in some infants with HIE, many infants with HIE will have significant lifelong disabilities despite receiving this treatment.

New routes towards reutericyclin analogues [PDF]
A range of N-acylpyrrolo[3,4-c]isoxazoles and derived N-5 acyltetramides has been prepared via a nitrile oxide dipolar cycloaddition approach, as analogues of the acyltetramic acid metabolite reutericyclin, of interest for their antibiotic potential ...

Substituent effects in isoxazoles: identification of 4-substituted isoxazoles as Michael acceptors
Crystallographic and theoretical studies have been used to investigate substituent effects, which are manifest in electrochemical and yeast-catalysed reactions of 4- and 5-acyl-, alkoxycarbonyl-, cyano- and phenyl-substituted isoxazoles. The results show that isoxazoles substituted at the 4-position with π-electron-withdrawing substituents have ...

The synthesis and reactivity of α-oxoketenes dithioacetals (S,S-acetals), general structure [(R¹C=OC(R²)=C(SR³)(SR4)], are reported. We also showed the application of S,S acetals as synthons for efficient synthesis of isoxazoles, pyrazoles ...

Synthetic isoxazole as antiplatelet agent
Abstract Nine synthetic isoxazoles were evaluated as antiplatelet agents and studied the possible mechanism of more active compound. The initial screening was evaluating all compounds against platelet aggregation assays. The most active compound was isoxazole 8 showing an inhibition of platelet aggregation around 70%. In subsequent experiments, ADP and

A novel iminoxyl radical-promoted dichotomous regioselective 5-exo-trig cyclization onto vinylic halogen/1,2-halogen radical shift sequence is developed for the synthesis of halomethyl isoxazoles/cyclic nitrones using β-halo-β,γ- and γ-halo-γ,δ ...

Reaction of enantiopure 3,4-dialkoxy-pyrroline N-oxides with benzyne affords the expected tetrahydrobenzo[d]pyrrolo[1,2-b]isoxazoles along with an unexpected 2,3-disubstitued-N-phenyl-pyrrole derived from an unprecedented rearrangement of the adduct of ...
