Abstract
In this review article, we describe the application, reactivity and synthesis of isoxazole derivatives,
more specifically, the application, reactivity, and synthesis of 3,5-disubstituted, 3,4-
disubstituted, and 3,4,5-trisubstituted isoxazole using the green method. We review the application of
isoxazole in material science, agriculture and pharmaceutical. In material science, isoxazole is used
as a photochromic, electrochemical probe for Cu<sup>2+</sup> and, given its optical properties, in dye-sensitized
solar cells, high energy material and liquid crystal. In agriculture, isoxazole is used as an insecticide
for managing Callosobruchus chinensis, Acaricidal activity against T. cinnabarinus, and herbicidal
activities of 2-cyanoacrylates containing isoxazole. In pharmaceutical, isoxazole shows anticancer,
antituberculosis, anti-inflammatory, and acetylcholinesterase inhibitors. Further, we describe various
reactions of isoxazole such as ring opens, bromination and iodination, thioynol ethers, intramolecular
SEAr reaction, arylation, cycloaddition and photocycloaddition, photoisomerization, Domino transformation
of isoxazoles to 2,4-dicarbonyl pyrroles and rearrangement. We also describe the synthesis
of 3,5-disubstituted, 3,4-disubstituted and 3,4,5-trisubstituted isoxazole using different methods.

Abstract
AbstractThe regiospecific 1,3-dipolar cycloaddition of 1,5-dihydropyrrol-2-one and arylnitrile oxides derivatives have been investigated. The asymmetric induction expected by the chiral centre of the 5-hydroxy-3-methyl-1,5-dihydropyrrol-2-one derivatives was very effective, single diastereoisomers anti-3 was formed. The diastereoselectivity was linked to the destabilization of the syn transition state as a result of the electrostatic repulsion between the hydroxy group of the dihydropyrrol-2-one derivatives and the atom oxygen of the dipole.

Abstract
A simple and efficient method for the stereoselective synthesis of isoxazoline/isoxazole-fused iminosugar derivatives has been developed using intramolecular nitrile oxide cycloaddition (INOC) as a key step. Iminosugar C-nitromethyl glycosides, derived from simple carbohydrates, served as excellent nitrile oxide precursors in 1,3-dipolar cycloaddition reactions. N-Alkenyl iminosugar C-nitromethyl glycosides afforded novel isoxazoline-fused indolizidine-, pyrrolizidine-, and quinolizidine-based iminosugars in excellent yields with a high degree of stereoselectivity, whereas N-alkynyl iminosugar C-nitromethyl glycosides furnished the corresponding isoxazole containing tricyclic iminosugars in very good yields.
