摘要:

建立了一种可见光驱动下焦磷酸硫胺素(ThDP)依赖酶与光催化剂协同催化的新方法, 实现了芳香醛与偶氮腈的自由基酰化反应, 高效合成了一系列β‑酮腈类化合物. 该体系利用光催化产生氰烷基自由基, 并与酶活性中心内由ThDP稳定的酮基自由基发生交叉偶联, 在温和条件下构建C—C键. 此反应具有广泛的底物适用性和良好的官能团兼容性. 本研究是首例光生物催化合成β‑酮腈的报道, 为绿色合成及酶催化非天然转化提供了新策略.

Abstract:

This paper reports a novel photobiocatalytic system that integrates thiamine diphosphate(ThDP)-dependent enzymes with photoredox catalysis to achieve radical acylation between aromatic aldehydes and azonitrile reagents under visible light irradiation. This method enables the efficient synthesis of β‑ketonitriles via cross-coupling of an enzyme-bound ThDP-derived ketyl radical and a photogenerated cyanoalkyl radical under mild conditions. The reaction exhibits a broad substrate scope and good functional group compatibility. This work represents the first example of synthesizing β‑ketonitriles via photobiocatalysis, offering a new strategy for sustainable synthesis and expanding the toolbox for non-natural enzyme catalysis.

Key words: Photobiocatalysis, Radical acylation, Thiamine diphosphate(ThDP), β-Ketonitrile
