硫醇的S-甲酰化是通过甲酸脱氢酶催化的酶促过程实现的,该酶将CO 2固定在底物上,这在调节活生物体的重要生物途径中起着至关重要的作用。通过化学方法实现这种反应性也可能是有利的,这将允许将CO 2固定在多种硫醇上。在这里,我们演示了在无金属条件下使用介离子N-杂环烯烃从CO 2制备S-甲酰硫醇的化学过程。该催化反应用于多样化从天然萜类化合物、脂肪醇、抗氧化剂和市售镇痛抗炎药物分子中获得的多种生物活性硫醇,以及13 C 标记的甲酰辅酶 A 的制备。此外,我们建立了在CO 2存在下完全无金属条件下合成乙烯基硫醚的一锅S-甲酰化-烯化工艺。总的来说,这项研究提供了一个将硫醇和CO 2转化为增值产品的平台。

We designed and synthesized a fatty aldehyde surrogate containing a formyl thioester group, which can be reduced by fatty aldehyde reductase (FALR) with stoichiometric formaldehyde generation. It can be rapidly visualized and quantified using the Purpald assay. We demonstrated its successful application in the high throughput screening of FALR engineering.
