Methyl 2-(5-oxo-4,5-dihydroisoxazol-3-yl)acetate (cas: 96530-57-3) belongs to isoxazole derivatives.Synthetically, isoxazoles serve as valuable precursors for the construction of diverse molecules, including many natural products. The electrophilic cyclization of various 2-alkynone O-methyl oximes with a wide range of substrates such as ICl, I2, Br2, PhSeBr, etc. provides a variety of 3,4,5-trisubstituted isoxazoles in good to excellent yields.Application of 96530-57-3

A new synthesis of 5,7-dicarboxy-2,1-benzisoxazolin-3-one was written by Kim, C. K.;Krasavage, B. A.;Maggiulli, C. A.. And the article was included in Journal of Heterocyclic Chemistry in 1985.Application of 96530-57-3 The following contents are mentioned in the article:

Condensation of isoxazolinone I and Me2NCH:C(CHO)CO2Et gave benzisoxazolinone II (R = Me, R1 = Et). Simple hydrolysis of the latter compound afforded the title compound (II, R = R1 = H). This study involved multiple reactions and reactants, such as Methyl 2-(5-oxo-4,5-dihydroisoxazol-3-yl)acetate (cas: 96530-57-3Application of 96530-57-3).
