A novel strategy towards the construction of highly diversified tetrahydroquinolinoisoxazole frameworks with high diastereoselectivity via intramolecular 1,3-dipolar nitrone cycloaddition reaction is described for the first time. All the synthesized tetrahydroquinolinoisoxazoles are new and obtained in excellent yields under catalyst free condition.
