## Abstract magnified image Asymmetric 1,3βdipolar cycloadditions of chiral nitrones to 1βpropeneβ1,3βsultone (**1**) were investigated. Chiral nitrones **6aβe** reacted with sultone **1** in toluene at 90 Β°C for 24β36 h to give the corresponding isoxazolidines in moderate yields with high regiose
