Synthesis of 3-Aminoisoxazoles via the Addition−Elimination of Amines on 3-Bromoisoxazolines
摘要:
A novel two-step procedure for the synthesis of 3-amino-5-substituted-isoxazoles Is described. In the presence of a base, readily available 3-bromoisoxazolines react with amines to afford 3-aminoisoxazolines. An oxidation protocol was developed for these heterocycles to provide 3-aminoisoxazoles in consistently high yield.

Silyl isoxazolines have been synthesized by [2 + 3] cycloaddition reaction of nitrileoxides and silylnitronates to vinyl- and allylsilanes. The direction of the cycloaddition reaction of nitrileoxides to trialkoxyvinylsilanes has been shown to depend on the nature of the substituents on silicon and on the method used to generate the nitrileoxides. The addition of silyl esters of aci-nitromethane
