  Oridamycins A and B, Anti-Saprolegnia parasitica Indolosesquiterpenes Isolated from Streptomyces sp. KS84

  摘要：

  Oridamycins A (1) and B (2) were isolated from the fermentation broth of Streptomyces sp. strain KS84 as selective anti-Saprolegnia parasitica antibiotics. Their structures were elucidated as pentacyclic indolosesquiterpenes by the combination of NMR and spectroscopic analyses. The absolute configuration of 1 was determined by ROESY analyses after the advanced Mosher analysis. Compound 1 exhibited anti-S. parasitica activity with an MIC value of 3.0 mu g/mL, but was much less active against the phytopathogenic fungus Phoma sp. and the yeast Saccharomyces cerevisiae.

  Total Synthesis of Oridamycins A and B

  摘要：

  The total synthesis of both oridamycin A and oridamycin B was accomplished starting from a common synthetic intermediate readily prepared from geranyl acetate. The sequence utilizes an oxidative radical cyclization to construct the trans-decalin ring system, setting three of four contiguous stereocenters in one operation. The carbazole nucleus was forged through a one-pot process entailing acid-promoted dehydration followed by 6 pi-electrocyclization/aromatization.

  Total syntheses of oridamycin A, triptoquinones B and C, and isoiresin are accomplished from a common intermediate prepared via iridium-catalyzed alcohol C-H tert-(hydroxy)prenylation - a byproduct-free process that forms an all-carbon quaternary stereocenter with excellent control of diastereo- and enantioselectivity.

  A variety of strategies were explored to form a chelated radical intermediate en route to xiamycin A, including enolate SET oxidation, oxo-vanadium oxidation, and atom-transfer cyclization. Unfortunately, none of these strategies provided the desired C16-epimeric trans-decalin. Exploratory studies on photoredox-catalyzed radical cyclizations yielded interesting results, including the formation of a

  设计了针对天然产物奥达霉素和厦霉素家族的统一合成策略，旨在从易于从乙酸香叶酯制备的通用合成中间体中获得几种天然产物。该策略的一部分已成功实现，最终合成了奥达霉素A和奥达霉素B。关键步骤包括Mn（III）介导的氧化自由基环化以构建反式-十氢化萘环和6π-电环化/芳香化序列生成2，3-稠合咔唑。奥立霉素B是通过后期的C–H氧化获得的，该氧化将C16甲基转化为羟甲基。探索了多种策略以形成通往霞霉素A的螯合自由基中间体，包括烯醇式SET氧化，氧-钒氧化和原子转移环化。不幸的是，这些策略都没有提供所需的C16-表异构反式-十氢化萘。上photoredox催化自由基环化探索性研究产生了有趣的结果，包括形成从photoredox催化的自由基环化的氧化终止引起的二环内酯，和双6-内与催化剂负载量低至0.01％（摩尔）环化。

  enantiospecific total syntheses of the indolosesquiterpenoids xiamycins A, C, F, H and oridamycin A have been accomplished. The syntheses, which commence from (R)‐carvone, employ a key photoinduced benzannulation sequence to forge the carbazole moiety characteristic of these natural products. Late‐stage diversification from a common intermediate enabled the first syntheses of xiamycins C and F, and an

  吲哚半萜类夏霉素 A、C、F、H 和 Oridamycin A 的发散性和对映特异性全合成已经完成。该合成从 ( R )-香芹酮开始，采用关键的光诱导苯并环化序列来形成这些天然产物的咔唑部分特征。常见中间体的后期多样化使得首次合成了夏霉素 C 和 F，并且意外的一锅氧化脱羧作用（这可能被证明是普遍的）导致了夏霉素 H。所有合成中间体和天然产物都经过了抗真菌测试活动。Xiamycin H 作为三种农业相关真菌病原体的抑制剂而出现。
