We report herein the selective hydroxylation of 10-undecenoic acid with a light-activated hybrid P450 BM3 enzyme. Under previously developed photocatalytic reaction conditions, only a monohydroxylated product is detected by gas chromatography. Hydroxylation occurs exclusively at the allylic position as confirmed from a synthesized authentic standard. Investigation into the stereochemistry of the reaction
我们在此报告了 10-十一碳烯酸与光活化杂种 P450 BM3 酶的选择性羟基化。在先前开发的光催化反应条件下,气相色谱仅检测到单羟基化产物。羟基化仅发生在烯丙基位置,如合成的可靠标准所证实。对反应立体化学的研究表明,以 85% ee 获得 R 对映异构体。酶促获得的 ( R )-9-羟基-10-十一碳烯酸是一种有价值的合成子,可用于各种天然产物,进一步扩展了光活化 P450 BM3 生物催化,并突出了与传统方法相比的优势。
Enantioselective Allylic Hydroxylation of ω-Alkenoic Acids and Esters by P450 BM3 Monooxygenase
allylic alcohols of ω‐alkenoic acids and derivatives thereof are highly important building blocks for the synthesis of biologically active compounds. The direct enantioselective CH oxidation of linear terminal olefins offers the shortest route toward these compounds, but known synthetic methods are limited and suffer from low selectivities. Described herein is an enzymatic approach using the P450
