- Lithiation occurs first at the 5-methyl group. Subsequent reaction with electrophiles can be followed by further lithiation of the 3-methyl, providing a route to substituted isoxazoles, and also to 1,3-diketones by acid hydrolysis or ß-aminoketones by hydrogenolysis: Tetrahedron Lett., 22, 3699 (1981):
