    Direct arylation represents a favourable alternative to traditional cross-coupling reactions and has found widespread use with simple aryls and robust heterocycles. Herein a direct arylation protocol has been optimised and applied to more delicate, privileged biological motifs. The intramolecular direct arylation of 2-pyrones, 2-coumarins, 2-pyridones and 2-quinolones occurs in very good to excellent

    synthesis of the pentaketide flaviolin and its dimeric derivative, and a wide range of pyrones and their coupled derivatives with flaviolin, as well as their halogenated derivatives. The addition of acyl-CoA oxidase to the pathway prior to the polyketide synthase resulted in unsaturated pyrone side chains, further broadening the product spectrum that can be achieved. The approach developed in this work
    在体外构建了一个合成代谢途径,包括来自天蓝色链霉菌的 III 型聚酮化合物合酶和来自大豆和烟熏蓝藻(氯过氧化物酶)的过氧化物酶。这导致合成了五肽黄素及其二聚衍生物,以及广泛的吡喃酮及其与黄素的偶联衍生物,以及它们的卤化衍生物。在聚酮合酶之前将酰基辅酶A氧化酶添加到途径中导致不饱和的吡喃酮侧链,进一步拓宽了可以实现的产物谱。因此,这项工作中开发的方法为在复杂天然产物衍生物的合成中利用生物催化提供了一种新模型。
