  oxidative rearrangement of anthraquinone natural products to xanthones in vivo. Many of these Baeyer-Villiger-like cleavages are believed to be carried out by cytochrome P450 enzymes. In the biosynthesis of the fungal carcinogen, aflatoxin, six cytochromes P450 are encoded by the biosynthetic gene cluster. One of these, AflN, is known to be involved in the conversion of the anthraquinone versicolorin A (3)

  长期以来，邻羧基二苯甲酮被认为是蒽醌天然产物在体内氧化重排为氧杂蒽酮的中间体。许多这些 Baeyer-Villiger 样裂解被认为是由细胞色素 P450 酶进行的。在真菌致癌物黄曲霉毒素的生物合成中，六种细胞色素 P450 由生物合成基因簇编码。其中之一，AflN，已知参与将蒽醌杂色素 A (3) 转化为氧杂蒽酮去甲基黄曲霉毒素 (5)，然后再转化为霉菌毒素。然而，芳基脱氧也在该整体转化中发生，并且被提议是由于需要 NADPH 依赖性氧化还原酶 AflM 具有活性才能发生该过程。审查了对其他真菌蒽醌 --> 氧杂蒽酮转化的了解，值得注意的是，邻羧基二苯甲酮 sulochrin (25) 在 geodin (26) 生物合成中的作用。在黄曲霉毒素途径中的诱变实验和这些生化先例的基础上，描述了带有稠合四氢双呋喃的四羟基-邻羧基二苯甲酮及其 15-脱氧同系物的全合成。合成的关键步骤需要在菊池条件下重排带有富电子苯环的

  作者：Jeremy D. Pettigrew、Peter D. Wilson

  DOI：10.1021/jo052371+

  日期：2006.2.17

  xyloketal A, B, C, D, and G have been prepared in a notably direct manner from 3-hydroxymethyl-2-methyl-4,5-dihydrofuran and a series of corresponding phenols. These syntheses featured a boron trifluoride diethyl etherate-promoted electrophilic aromatic substitution reaction as a key step. In the case of the synthesis of analogues of xyloketal A, the process was found to be highly efficient (up to 93% yield)

  由3-羟甲基-2-甲基-4，5-二氢呋喃和一系列相应的酚以明显直接的方式制备了一系列天然产物木酮缩醛A，B，C，D和G的脱甲基类似物。这些合成的关键步骤是三氟化硼二乙基醚化物促进的亲电子芳族取代反应。在合成木酮缩醛A的类似物的情况下，发现该方法是高效的（产率高达93％）。考虑到该转化至少涉及六个单独的反应，这些反应产物的最佳分离产率是显着的。而且，这些合成研究为木酮缩醛天然产物的可能的生物起源提供了重要的见识。

  作者：David Conradt、Bianca Hermann、Stefan Gerhardt、Oliver Einsle、Michael Müller

  日期：2016.12.12

  Phloroglucinol reductases (PGRs) are involved in anaerobic degradation in bacteria, in which they catalyze the dearomatization of phloroglucinol into dihydrophloroglucinol. We identified three PGRs, from different bacterial species, that are members of the family of NAD(P)H‐dependent short‐chain dehydrogenases/reductases (SDRs). In addition to catalyzing the reduction of the physiological substrate

  间苯三酚还原酶（PGR）参与细菌的厌氧降解，其中它们催化间苯三酚脱芳香化为二氢间苯三酚。我们鉴定了来自不同细菌物种的三个PGR，它们是NAD（P）H依赖的短链脱氢酶/还原酶（SDR）家族的成员。除了催化还原生理底物外，这三种酶还显示出对2,4,6-三羟基苯甲醛，2,4,6-三羟基苯乙酮和2,4,6-三羟基苯甲酸甲酯的活性。PGRcl的结构解析以及与已知SDR的比较显示出高度的保守性。几个氨基酸位置被鉴定为在PGR亚家族中是保守的，并且可能与底物分化有关。
