What is the structure of Isoxazole?
Isoxazole is a monocyclic heteroarene with a structure consisting of a 5-membered ring containing three carbon atoms and an oxygen and nitrogen atom adjacent to each other. It is the parent of the class of isoxazoles. It is a mancude organic heteromonocyclic parent, a monocyclic heteroarene and a member of isoxazoles.
How do you synthesis Isoxazole?
Pyrazole or isoxazole derivatives are prepared by a palladium-catalyzed four-component coupling of a terminal alkyne, hydrazine (hydroxylamine), carbon monoxide under ambient pressure, and an aryl iodide.
Which of the following contains Isoxazole?
An isoxazolyl group is found in many beta-lactamase-resistant antibiotics, such as cloxacillin, dicloxacillin and flucloxacillin. Leflunomide is an isoxazole-derivative drug. Examples of AAS containing the isoxazole ring include danazol and androisoxazole.
Is Isoxazole aromatic?
Isoxazole is an aromatic system and its aromaticity is highly influenced due to the presence of O and N heteroatoms in the five-membered ring.
What are isoxazole derivatives?
Leflunomide, an isoxazole derivative, is a product of agricultural pesticide research that was found to be both antiinflammatory and immunosuppressive [5].
What are Isoxazoles used for?
Isoxazoles are an important class of heterocycles, which are largely employed in the area of pharmaceuticals and therapeutics such as insecticidal, antibacterial, antibiotic, antitumour, antifungal, antituberculosis, anticancer and ulcerogenic.

Is ethylene dibromide toxic to humans?
Ethylene Dibromide (EDB) The U.S. Environmental Protection Agency (EPA) considers EDB an extremely hazardous chemical. In 1948, EDB was registered for use in the United States as an insect killer.
What is isoxazole-5-carbaldehyde?
Isoxazole-5-carbaldehyde was prepared by the manganese dioxide oxidation of 5-hydroxymethylisoxazole 〈67T4697〉, the latter being formed from sodium fulminate and propargyl alcohol in greater than 90% yield. A variety of other isoxazole aldehydes has also been reported 〈62HC (17)1, p. 77〉.
How does ethylene dibromide enter the body?
Ethylene Dibromide (EDB) EDB can enter the body when people breathe its vapors. People using EDB-contaminated water for household purposes such as washing or bathing may inhale small amounts of EDB evaporating from contaminated water into the air. Past exposures may have occurred as soil and food products were treated with EDB to remove insects.
