In a recent JOC paper, Enamine chemists reported a comprehensive study of regioselective [3 + 2] cycloaddition reactions – an efficient approach towards 3,5-disubstituted isoxazole building blocks bearing mono-, di- or trifluoromethyl substituents. More than 100 derivatives were obtained on up to 130 g scale, and multigram quantities of representative examples are available from EnamineStore at the isoxazole library.
