In, out, olefin about: A ruthenium hydride complex derived from the Grubbs second‐generation metathesis catalyst has proven to be an efficient catalyst for the selective isomerization of terminal olefins to the corresponding propenyl derivatives (see scheme). This methodology has been applied in a number of syntheses to enable access to complex natural products. Cy=cyclohexyl, Mes=mesityl, MOM=methoxymethyl.

末端烯烃的钌催化异构化：在合成中的应用

从里到外，烯烃有关：事实证明，衍生自Grubbs第二代复分解催化剂的氢化钌络合物是将末端烯烃选择性异构化为相应的丙烯基衍生物的有效催化剂（参见方案）。该方法已应用于多种合成方法中，从而能够获取复杂的天然产物。Cy ＝环己基，Mes ＝间苯三甲，MOM ＝甲氧基甲基。
