  • Chiral Boron Complex-Promoted Asymmetric Diels–Alder Cycloaddition and Its Application in Natural Product Synthesis
    作者:Xia Li、Jianguang Han、Alexander X. Jones、Xiaoguang Lei

    日期:2016.1.15
    An efficient method for the asymmetric Diels–Alder cycloaddition of 2′-hydroxychalcones with acyclic or cyclic dienes has been successfully developed. The Diels–Alder cycloaddition is mediated by a chiral boron complex with VANOL, affording the corresponding products in high yields and with excellent diastereo- and enantioselectivities. This reaction enabled the enantioselective construction of cyclohexene
    已经成功地开发了一种有效的方法,用于非对称或对称的二烯与二烯基羟基二烯的Diels-Alder环加成反应。Diels–Alder环加成反应是由手性硼与VANOL配合物介导的,可提供高收率的相应产物,并具有出色的非对映和对映选择性。该反应使环己烯骨架的对映选择性结构对于许多Diels-Alder型天然产物(-)-烟酰胺C,(-)-泛地汀A,(-)-kuwanon I,(+)-的全合成至关重要kuwanon J和(-)-溴亚砜A和B.

    of Diels–Alder reactions in the biosynthesis of numerous secondary metabolites, no naturally occurring stand-alone Diels–Alderase has been demonstrated to catalyse intermolecular Diels–Alder transformations. Here we report a flavin adenine dinucleotide-dependent enzyme, Morus alba Diels–Alderase (MaDA), from Morus cell cultures, that catalyses an intermolecular [4+2] cycloaddition to produce the natural
    狄尔斯-阿尔德反应是合成化学中碳-碳键的立体有择构造中最强大,应用最广泛的方法之一。尽管Diels-Alder反应在许多次生代谢产物的生物合成中很重要,但尚无天然存在的独立Diels-Alderase能够催化分子间Diels-Alder转化。在这里,我们报告黄素腺嘌呤二核苷酸依赖性酶,桑 白尔斯- Alderase(MAD​​A),从桑细胞培养,可催化分子间[4 + 2]环加成反应,从而以高效率和对映选择性产生天然异戊二烯基黄酮类查克拉霉素。密度泛函理论计算和动力学同位素效应的初步测量建立了一个协调但异步的周环途径。结构指导的诱变和对接研究表明,MaDA与二烯和亲二烯体的相互作用可催化[4 + 2]环加成反应。MaDA对二烯和亲二烯体均显示出底物混杂性,这使得能够方便地合成结构多样的天然产物。我们还报告了用于发现MaDA的基于生物合成中间探针(BIP)的目标识别策略。

  • DIELS-ALDERASE AND USE THEREOF
    申请人:Peking University

    公开(公告)日:2021-05-20
    The present invention provides a Diels-Alderase and use thereof, and belongs to the field of gene engineering technology. The Diels-Alderase is MaDA, and its amino acid sequence and gene sequence are represented by SEQ ID Nos. 1 and 2, respectively. The present invention also provides MaDA-1 and MaDA-2, both of which are homologous proteins of MaDA, and their amino acid sequences are represented by SEQ ID Nos. 10 and 12, respectively. The present invention has discovered that MaDA and its homologous proteins from Morus alba can stereospecifically synthesize natural products of endo configuration, and prepare D-A type natural products and their analogs in vitro using chalcones and dehydroprenyl-containing compounds as substrates, which helps to develop and utilize the medicinal value of such natural products, and also provides a possibility to synthesize other six-membered ring-containing important chemical precursors or natural products.
