A series of Grubbs‐type catalysts that contain lipase‐inhibiting phosphoester functionalities have been synthesized and reacted with the lipase cutinase, which leads to artificial metalloenzymes for olefin metathesis. The resulting hybrids comprise the organometallic fragment that is covalently bound to the active amino acid residue of the enzyme host in an orthogonal orientation. Differences in reactivity
已经合成了一系列含有抑制脂肪酶磷酸酯功能的Grubbs型催化剂,并与脂肪酶角质酶反应,这导致了用于烯烃复分解的人造金属酶。所得的杂合体包含以正交方向共价结合到酶宿主的活性氨基酸残基上的有机金属片段。在反应性以及通过官能化抑制剂的活性位点的可接近性差异通过锚定基序和取代基在N的变化变得明显-杂环卡宾配体。这些观察导致了杂交体的设计,是活跃在闭环复分解和交叉复分解N,N-二烯丙基对-分别是甲苯磺酰胺和烯丙基苯,后者是人工金属酶领域中的第一个实例。
