## Abstract magnified image Asymmetric 1,3‐dipolar cycloadditions of chiral nitrones to 1‐propene‐1,3‐sultone (**1**) were investigated. Chiral nitrones **6a‐e** reacted with sultone **1** in toluene at 90 Β°C for 24‐36 h to give the corresponding isoxazolidines in moderate yields with high regiose
