3-Benzoylisoxazolines by 1,3-Dipolar Cycloaddition: Chloramine-T-Catalyzed Condensation of α-Nitroketones with Dipolarophiles

Molecules. 2021 Jun 8;26(12):3491. doi: 10.3390/molecules26123491.

Abstract

In this study, 3-benzoylisoxazolines were synthesized by reacting alkenes with various α-nitroketones using chloramine-T as the base. The scope of α-nitroketones and alkenes is extensive, including different alkenes and alkynes to form various isoxazolines and isoxazoles. The use of chloramine-T, as the low-cost, easily handled, moderate base for 1,3-dipolar cycloaddition is attractive.

Keywords: 1,3-dipolar cycloaddition; alkenes; chloramine-T; isoxazolines; α-nitroketones.
