摘要：

The 1,3-dipolar cycloaddition reaction of N-benzyl-C-(hetaryl)nitrones gave preferentially trans-substituted 3,5-disubstituted isoxazolidines (endo approach) which can be further converted into the corresponding 5-hetaryl-3-hydroxy-2-pyrrolidinones. A theoretical study of the cycloaddition reaction by using both semiempirical (AM1, PM3) and ab initio (HF/3-21G, HF/6-31G*//3-21G) methods has also been carried out. In all cases the obtained results are in good qualitative agreement with the experimental observations.
