New functionalized isoxazolines were effeciently and easily prepared from limonene. The procedure involves a peri- and regioselective 1,3-dipolar cycloaddition of nitrile oxides on the monoterpene external double bond, followed by a highly chemoselective RuCl3-NaIO4 oxidative cleavage of the internal one. All the newly prepared isoxazolyl-ketoacids were fully characterized from their spectroscopic data.
