    Natural product synthesis from (8aR)- and (8aS)-bicyclofarnesols: synthesis of (+)-wiedendiol A, (+)-norsesterterpene diene ester and (−)-subersic acid
    摘要:
    Both enantiomers (8aR)-7 and (8aS)-7 of bicyclofarnesol were synthesized from the enzymatic resolution products (1R,4aR,8aR)-1,2,3,4,4a,5,6,7,8,8a-decahydro-5,5,8a-trimethyl-2-oxo-trans-naphthalene-1-methanol-2-ethylene acetal (8aR)-5 (98% ee) and acetate of(1S,4aS, 8aS)-1,2,3,4,4a, 5,6,7,8,8a-decahydro-5,5,8a-trimethyl-2-oxo-trans-naphthalene-1-methanol-2-ethylene acetal (8aS)-6 (> 99% ee), respectively. The formal synthesis of (+)-wiedendiol 1 was achieved via a coupling reaction of an ate complex derived from 1,2,4-trimethoxybenzene with allyl bromide (8aS)-8 derived from (8aS)-7. The total synthesis of (+)-norsesterterpene diene ester 2 was achieved, based on the synthesis of (13E,10S)-alpha,beta-unsaturated aldehyde 12, derived from (8aS)-7, followed by the selective construction of the (3E,5E)-diene moiety including a C(2)-stereogenic centre in (+)-2. The total synthesis of (-)-subersic acid 3 was carried out based on a Stille coupling between allyl trifluoroacetate congener 25c, derived from (8aR)-7, corresponding to the diterpene part, and aryl stannane congener 26 in the presence of Pd catalyst and CuI as an additive.

    模拟 Drimentines 生物合成的主要事件:Δ8'-Isodrimentine A 和相关化合物的合成
    摘要:
    Drimentines 是生物合成的四环生物碱家族,源自倍半萜烯单元缩合到环二肽上。本文描述了 drimentines 的融合“吡咯并吲哚啉-二酮哌嗪”核心的直接组装,并用于合成 Δ8'-isodrimentine A。该策略涉及通过 drimane 型十氢化萘对含色氨酸的环二肽进行生物启发的吲哚脱芳构化然后以不间断的反应序列分子内捕获所得的假吲哚中间体。起始二酮哌嗪是通过经典的肽偶联和来自 (+)-sclareolide 的 drimane 型十氢化萘制备的。还报道了一种具有线性倍半萜烯单元的完全仿生方法,并导致法呢基化吡咯并吲哚啉-二酮哌嗪,

  • Synthesis of the Racemate of the Stereoisomer at C-6a of BE-40644, a Bioactive Metabolite of Actinoplanes sp. with a Sesquiterpene-substituted p-Benzoquinone Structure
    作者:Hisayuki TSUJIMORI、Kenji MORI
    DOI:10.1271/bbb.65.167
    日期:2001.1
    BE-40644 is a tetracyclic metabolite of Actinoplanes sp. A 40644 possessing a sesquiterpene-substituted p-benzoquinone structure with cis-fused B/C ring stereochemistry that inhibits the human thioredoxin system as the well as the growth of several cancer cell lines. Its B/C trans-fused stereoisomer at C-6a was synthesized as a racemate starting from geranylacetone and 3,5-dihydroxybenzoic acid.
    BE-40644 是来自 Actinoplanes sp. A 40644 的一种四环代谢物,具有一个与顺式融合的 B/C 环立体化学的单萜取代对苯醌结构,能够抑制人类硫氧还蛋白系统以及几种癌细胞系的生长。其在 C-6a 处的 B/C 反式融合立体异构体是以香叶酮和 3,5-二羟基苯甲酸为起始物合成的外消旋体。

    A mixture of (13E,17E)-12-phenylsulfonylbicyclogeranylfarnesol tetrahydropyranyl ether (8) and (13E,17E)-12-phenylsulfonylbicyclogeranylfarnesol (9) was formed by superacid low-temperature cyclization of exclusively trans-8-phenylsulfonylgeranylfarnesol tetrahydropyranyl ether (1). The structures of 8 and 9 were established using spectral data. The optically active form of 9 was also confirmed by retrosynthesis from (+)-sclareolide (10).

    Two new efficient methods for the regioselective homocoupling of allylic halides using either catalytic TiIII or the combination Mn/ZrIV catalyst have been developed. The regio- and stereoselectivity of the process proved to increase significantly when the Mn/ZrIV catalyst is used as the coupling reagent and when cyclic substituted allylic halides are used as substrates. The use of Lewis acids such

  • Enantioselective Annulation Using Nazarov Reagent: Synthesis of (+)-Preoleanatetraene
    作者:Alejandro F. Barrero、Simeón Arseniyadis、José F. Moral、M. Mar Herrador、Antonio Rosellón
    DOI:10.1055/s-2005-864798
    日期:——
    The enantioselective synthesis of preoleanatetraene (1) has been accomplished via a convergent approach of two C-15 synthons. The key step of this synthesis has been an interesting enantio­selective variant of the Robinson annulation using the Nazarov reagent and a chiral enamine to obtain the bicyclic moiety A. This asymmetric methodology opens the access to other irregular triterpene skeletons whose biogenetic implication should not be underestimated.
    预奥利烯四烯(1)的对映选择性合成已通过两种C-15合成单元的汇聚性方法完成。该合成的关键步骤是使用奈萨洛夫试剂和手性烯胺进行的一种有趣的对映选择性罗宾逊环化反应,以获得双环结构A。这种不对称方法学为其他不规则三萜骨架的获取提供了可能,其生物合成的意义不容小觑。

    method for providing enantiomerically pure bi-, tri-, and tetracyclic frameworks having a 1,1,5-trimethyl-trans-decalin nucleus, and demonstrated their utility for terpenoid synthesis. Thus, we achieved the stereocontrolled total syntheses of (+)-acuminolide as a bicyclic, (−)-spongianolide A as a tricyclic, and (+)-scalarenedial as a tetracyclic terpenoid from the corresponding optically pure cyclic
    我们已经开发了一种简单而实用的方法,可提供对映体纯的具有1,1,5-三甲基-反式十氢化萘核的双,三和四环骨架,并证明了它们可用于合成萜类化合物。因此,我们从相应的光学纯的环状β-酮酸酯中获得了立体控制的(+)-um啶内酯为双环,(-)-海绵状内酯A为三环和(+)-scal烯二醛作为四环萜烯的立体合成。通过重复相同的环构建方法,包括用路易斯酸将烯烃环化,然后分别使用手性助剂进行缩醛形成,进行简单的光学拆分,即可获得环戊二烯。这是合成具有1,1,5-三甲基-反式的对映体纯的环状萜类化合物的通用且有价值的策略-萘烷核。
