enantioselectivity

1.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、手性辅、手性3种策略,分别控制反应的非对映选择性和对映选择性。

2.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-L-脯酸-3,5-二甲苯胺作添加，手性选择性也较好，但由于含有苯环，紫外吸收增，波动严重。
