‘disarming’ a terminal alkene by substitution with a bulky silyl blocking group has been developed. In a series of model studies, sequential selective ring-closing metathesis of trienes followed by selective mono-hydrogenation of the resulting diene is described. The bulky silylated alkene is activated for a subsequent cross-metathesis reaction with a range of diverse alkenes by protodesilylation.
已经开发了通过用庞大的甲硅烷基保护基团取代来“解除”末端烯烃的合成策略。在一系列模型研究中,描述了三烯的顺序选择性闭环复分解,然后对所得二烯进行选择性单氢化。大量的甲硅烷基化的烯烃被活化,用于随后通过原去甲硅烷基化与一系列不同的烯烃进行交叉复分解反应。
