cross-metathesis is the key step. This reaction has proved to be highly regioselective, allowing the combination of α- or β-ionone derivatives having a 1,1-disustituted olefin with trisubstituted alkenes. The stereochemistry of the newly formed olefins has been established by spectroscopic means.
使用交叉复分解是关键步骤的策略已制备了三个系列的三孢菌素。已证明该反应是高度区域选择性的,使得具有1,1-取代的烯烃的α-或β-紫罗兰酮衍生物与三取代的烯烃结合。通过光谱方法已经确定了新形成的烯烃的立体化学。
