Light‐driven activation of redox enzymes is an emerging route for sustainable chemical synthesis. Among redox enzymes, the family of Old Yellow Enzyme (OYE) dependent on the nicotinamide adenine dinucleotide cofactor (NADH) catalyzes the stereoselective reduction of α,β‐unsaturated hydrocarbons. Here, we report OYE‐catalyzed asymmetric hydrogenation through light‐driven regeneration of NADH and its
光驱动氧化还原酶的激活是可持续化学合成的新兴途径。在氧化还原酶中,依赖烟酰胺腺嘌呤二核苷酸辅因子(NADH)的老黄酶(OYE)家族催化α,β-不饱和烃的立体选择性还原。在这里,我们报告了零维光催化剂N掺杂的碳纳米点(N-CD)通过光驱动的NADH及其类似物(mNADHs)的光驱动再生,生成了OYE催化的不对称氢化。我们的光谱和光电化学分析证实了光诱导电子从N-CD转移到有机金属电子介体(M)上以实现辅助因子的高度区域选择性再生。光触发了NAD +和mNAD +的减少在N-CD和M的配合下,辅因子的还原行为取决于其自身的还原峰电位。再生的辅因子随后将氢化物递送至OYE,以优异的生物催化效率将多种底物进行立体选择性转化。
