reactions are performed in high yields with considerable diastereoselectivities. Evidence for the preferred conformation of the enoates in the transition state of the nitrile oxide addition is provided and the stereoselectivity of nitrone additions is discussed.
使用简单的手性酯,可以以高收率和相当的非对映选择性进行环加成反应。提供了在腈氧化物添加的过渡态中烯酸酯的优选构象的证据,并且讨论了腈添加的立体选择性。
