Asymmetric 1,3-dipolar cycloaddition reactions of nitrones with (S)-(-)-4-benzyl-N-methacryloyl-2-oxazolidinone The [3+2]-nitrone-mediated cycloaddition reaction of (S)-(-)-4-benzyl-N-methacryloyl-2-oxazolidinone has been applied to the synthesis of highly substituted isoxazolidines with controlled stereochemistry. The absolute configuration of the major diastereoisorner derived from the reaction between
