Three strategies (additive, chiral auxiliary or chiral reagent) were developed to improve the diastereoselectivity or enantioselectivity of the ylide cyclopropanation reactions.
通过添加剂、手基、手试剂等3种策略,分别控制反应的非对映选择和对映选择。

The enantioselectivity of N-dodecanoyl-L-proline-3,5-dimethyl-anilide is also good, but the basic line fluctuates strongly due to containing benzene ring in its molecular structure.
虽然用N-十二酰基-L-脯酸-3,5-二甲基苯胺作添加剂,手选择也较好,但由于含有苯环,紫外吸收增强,基线波动严。
