the development of several efficient catalytic cross-metathesis strategies, which provide direct access to a considerable range of Z- or E-di-substituted cyano-substituted alkenes or their corresponding tri-substituted variants. Depending on the reaction type, a molybdenum-based monoaryloxide pyrrolide or chloride (MAC) complex may be the optimal choice. The utility of the approach, enhanced by an easy
腈存在于许多生物活性化合物中,属于有机化学中用途最广泛的官能团之一。尽管最近有许多显着的进步,但是,没有方法可用于制备二或三取代的烯基腈。涉及范围广并且可以以高立体异构体纯度递送所需产物的相关方法尤其缺乏。在这里,我们描述了几种有效的催化交叉复分解策略的发展,这些策略提供了直接进入相当大范围的Z-或E-二取代的氰基取代的烯烃或其相应的三取代变体的途径。取决于反应类型,基于钼的单芳氧基吡咯化物或氯化物(MAC)络合物可能是最佳选择。该方法的实用性,
