of Ru–alkylidene olefin metathesis catalysts with specialized properties is reported. This strategy utilizes a late stage, utilitarian Hoveyda-type ligand derived from tyrosine, which can be accessed via a multigram-scale synthesis. Further functionalization allows the catalyst properties to be tuned, giving access to modified second-generation Hoveyda–Grubbs-type catalysts. This divergent synthetic
据报道,一种简单通用的方法可用于获得具有特殊性能的新的Ru-亚烷基烯烃复分解催化剂系列。该策略利用了从酪氨酸衍生而来的后期功利主义的霍维达型配体,该配体可以通过多克级合成进行访问。进一步的功能化使催化剂的性能得以调整,从而获得了改良的第二代Hoveyda-Grubbs型催化剂。这种不同的合成方法可用于获得固体负载的催化剂和在无溶剂和水性条件下起作用的催化剂。
