Abstract
We describe a general method for the synthesis of 5-(trifluoromethyl)isoxazoles by denitrogenative cyclization of vinyl azides with trifluoroacetic anhydride in the presence of NEt3. The scope of this protocol was further extended to the synthesis of perfluoroalkylated isoxazoles. This reaction allows facile synthesis of structurally diverse 5-(perfluoroalkyl)isoxazole derivatives with various vinyl azides.
