A surprising new route to 4-nitro-3-phenylisoxazole
A one-pot synthesis of 4-nitro-3-phenylisoxazole has been carried out by treatment of cinnamyl alcohol dissolved in acetic acid with sodium nitrite; in addition, 4-phenyl-3-furoxanmethanol was obtained in 40% yield.
متن کاملExperimental 3-nitro-4-hydroxyphenylarsonic acid toxicosis in pigs.
Five times the recommended dose of 3-nitro-4-hydroxyphenylarsonic acid (187.5 mg kg-1) induces a pathognomonic clinical syndrome in pigs. The main clinical features are not continually present but are inducible only by exercise. From day 11 on the experimental diet a nervous syndrome was inducible. This manifested as muscle tremors and clonic convulsive episodes. Paraparesis developed by day 22...
متن کامل3-Nitro-4-(propylamino)benzonitrile
In the title compound, C(10)H(11)N(3)O(2), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 1.3 (3)°] and forms an intra-molecular amine-nitro N-H⋯O hydrogen bond. In the crystal, weak inter-molecular aromatic C-H⋯O(nitro) hydrogen bonds link the mol-ecules. Weak aromatic ring π-π inter-actions [minimum ring centroid separation = 3.7744 (13) Å] are also present.
متن کاملConjugation of nitrated acetaminophen to Der p1 amplifies peripheral blood monocyte response to Der p1
BACKGROUND An association of acetaminophen use and asthma was observed in the International Study of Asthma and Allergies in Childhood study. However there are no clear mechanisms to explain an association between acetaminophen use and immunologic pathology. In acidic conditions like those in the stomach and inflamed airway, tyrosine residues are nitrated by nitrous and peroxynitrous acids. The...
