Synthesis of 3-Substituted 5-Arylisoxazoles from α,β-Unsaturated Oximes

The synthesis of 3-substituted 5-arylisoxazoles from oximes of α,β-unsaturated ketones is studied. The formation of the isoxazole derivatives takes place by cyclization of oximes in the presence of iodine and potassium iodide. The presence of isoxazoline

SYNTHESIS OF ISOXAZOLE DERIVATIVES IN REACTION OF 2-HYDROXYPHENYLCARBONYL COMPOUNDS OR 1,3-DIKETONES WITH HYDROXYLAMINE-O-SULFONIC ACID

2-Hydroxybenzaldehyde 1a and 2-hydroxyacetophenone 1b react with hydroxylamine-O-sulfonic acid (HSA) yielding the corresponding oxime hydrogensulfates 2a and 2b, separated as potassium salts.These salts undergo conversion with good yields to benzisoxazole 3a and 2-methylbenzoxazole 3b, respectively.In similar reaction of 1,3-diketones, both cyclic and acyclic 1c-k with HSA, isoxazole derivatives 3c-k were obtained.
