The diastereoselectivities of epoxidations of diene amides 1b, 7, and 9 appear to depend on steric approach control with the involvement of amide conformers analogous to that observed by X-ray diffraction studies of epoxide 8 (Figure 1). This mechanistic framework should be useful for predicting the reactivity of diene amides related to 7 with other electrophilic reagents.
二烯酰胺1b,7和9的环氧化的非对映选择性似乎取决于空间方法的控制,其中酰胺构象物的参与类似于环氧化物8的X射线衍射研究所观察到的(图1)。该机理框架对于预测与7有关的二烯酰胺与其他亲电试剂的反应性应该是有用的。
