  Allyl/propenyl phenol synthases from the creosote bush and engineering production of specialty/commodity chemicals, eugenol/isoeugenol, in Escherichia coli

  摘要：

  The creosote bush (Larrea tridentata) harbors members of the monolignol acyltransferase, allylphenol synthase, and propenylphenol synthase gene families, whose products together are able to catalyze distinct regiospecific conversions of various monolignols into their corresponding allyl- and propenyl-phenols, respectively. In this study, co-expression of a monolignol acyltransferase with either substrate versatile allylphenol or propenylphenol synthases in Escherichia coli established that various monolignol substrates were efficiently converted into their corresponding allyl/propenyl phenols, as well as providing proof of concept for efficacious conversion in a bacterial platform. This capability thus potentially provides an alternate source to these important plant phytochemicals, whether for flavor/fragrance and fine chemicals, or ultimately as commodities, e.g., for renewable energy or other intermediate chemical purposes. Previous reports had indicated that specific and highly conserved amino acid residues 84 (Phe or Val) and 87 (Ile or Tyr) of two highly homologous allyl/propenyl phenol synthases (circa 96% identity) from a Clarkia species mainly dictate their distinct regiospecific catalyzed conversions to afford either allyior propenyl-phenols, respectively. However, several other allyl/propenyl phenol synthase homologs isolated by us have established that the two corresponding amino acid 84 and 87 residues are not, in fact, conserved.

  Dirigent 蛋白指导不对称异偶联合成复杂的天然产物类似物

  摘要：

  Phenylpropanoids 是一类在植物中发现的丰富的结构单元，来源于苯丙氨酸和酪氨酸。苯丙烷聚合产生第二丰富的生物聚合物木质素，而立体和位点选择性偶联产生一系列具有强生物活性的木脂素天然产物，包括拓扑异构酶抑制剂和化疗药物依托泊苷。依托泊苷生物合成的一个关键步骤涉及一种植物指示蛋白，该蛋白促进松柏醇（一种常见的苯丙素）选择性二聚化，形成 (+)-松脂醇，一种关键的 C 2对称通路中间体。尽管这种偶联反应具有优雅和快速组装依托泊苷支架的能力，但尚未利用定向蛋白来生成其他复杂的木脂素天然产物。在这里，我们证明了来自鬼臼属植物的致敏蛋白与漆酶结合可以引导异源天然和合成松柏醇类似物的偶联，用于松脂醇类似物的对映选择性合成。这种复杂性产生的途径非常直接和有效：三个新键和四个立体中心在一个步骤中由两种不同的非手性单体产生。我们预计我们的结果将使难以获得的非天然木脂素类似物和依托泊苷衍生物的生物

  The invention relates to a method for producing a cross-coupling product of a benzenoid dizonium salt according to the general formula (I), wherein the groups R 1 , R 2 , R 3 , R 4 , and R 5 represent hydrogen, halogen, an alkyl, alkenyl, aryl, alkoxy, aryloxy, nitro, cyano, hydroxy, acetyl, and/or diazo groups independently of each, and X represents BF 4 , Cl, F, SO 3 CH 3 , CO 2 CH 3 , PF 6 , ClO 2 CH 3 , or CIO 4 , comprising the following steps: (a) providing a benzenoid amide, which with the exception of the diazo function has the same substituents R 1 , R 2 , R 3 , R 4 , and R 5 as the benzenoid diazonium salt of the general formula (I), and hydrolytically cleaving the amide to form an amine or providing a corresponding amine, (b) diazotizing the amine thus obtained or provided with a nitrite, and (c) subsequently reacting the benzenoid diazonium salt with a coupling partner in the presence of a catalyst to form a cross-coupling product, wherein the coupling parter is represented by the general formula (II), R 6 , R 7 , and R 8 are the same or different and represent hydrogen, carboxyalkyl groups, carboxyaryl groups, alkyl groups, aryl groups, alkoxy groups, aryloxy groups, wherein the groups can each contain Si, N, S, O, and or halogen atoms, or R 6 and R 7 with the double bound form an aromatic ring, which can be provided with R 8 and one to four further substituents, independently of each other, selected from the group comprising a straight-chain or branched (C 1 -C 6 ) alkyl group, a (C 3 -C 7 ) cycloalkyl group, a straight-chain or branched (C 1 -C 6 ) alkenyl group, a straight-chain or branched (C 1 -C 6 ) alkyoxy group, halogen, the hydroxy group, an amino, di(C 1 -C 6 ) alkylamino, nitro, acetyl, cyan, benzyl, 4-methoxybenzyl, 4-nitrobenzyl, phenyl, and 4-methoxyphenyl group and represents Y=H, —B(OR) 2 , —SnR 3 , —ZnR, —SiR 3 , or Mg (halogen), and wherein at least the steps (b) and (c) are performed without intermediate isolation of an intermediate product. According to said method, cross-couplings can be performed more simply and with improved yield without the hydroxyl group in aromatic reactants containing hydroxyl groups having to be provided with a protective group.

  Herein we report the palladium-catalyzed isomerization of highly substituted allylic alcohols and alkenyl alcohols by means of a single catalytic system. The operationally simple reaction protocol is applicable to a broad range of substrates and displays a wide functional group tolerance, and the products are usually isolated in high chemical yield. Experimental and computational mechanistic investigations

  在此，我们报告了通过单一催化体系钯催化的高度取代的烯丙醇和链烯醇的异构化。操作简单的反应方案适用于广泛的底物，并显示出广泛的官能团耐受性，并且产物通常以高化学产率分离。实验和计算机制研究为由重复迁移插入/β-H 消除序列组成的链行走过程提供了补充和收敛的证据。有趣的是，在烯丙醇异构化过程中，催化剂不会从底物上解离，而当烷基链上存在额外的取代基时，它会在烯醇异构化过程中脱离。

  Two western red cedar pinoresinol‐lariciresinol reductase (PLR) homologues were studied to determine their enantioselective, substrate versatility, and kinetic properties. PLRs are downstream of dirigent protein engendered, coniferyl alcohol derived, stereoselective coupling to afford entry into the 8‐ and 8′‐linked furofuran lignan, pinoresinol.

  研究了两个西部红柏松脂松香醇-larresresinol还原酶（PLR）的同系物，以确定它们的对映选择性，底物通用性和动力学性质。PLR位于产生的稀疏蛋白质，针叶树醇衍生的立体选择性偶联的下游，以使其进入8和8'连接的呋喃呋喃木脂体木脂松酚。我们的研究表明，每个PLR同源物都可以通过修饰的芳环取代基对映异构地代谢不同的呋喃呋喃木脂素，但是其中C4 / C4'上的酚基对于催化是必不可少的。这些结果与PLR活性部位中醌甲基化物中间体的形成是一致的。定点诱变和动力学测量提供了对影响对映选择性和动力学性质的因素的进一步了解。根据这些数据，
