ChemInform Abstract: Synthesis of Some Novel Class of Isoxazoline and Isoxazolidine Derivatives in Ionic Liquid via 1,3‐Dipolar Cycloaddition Reaction of Dihydropyran Derived Nitrones and Their Antimicrobial Activities.

Abstract

AbstractNitrones (III) generated in situ from dihydropyran (I) and hydroxylamines (II) undergo further cycloaddition with alkynes (III) or methacrolein (VI) to give title compounds (V) or (VII).
