  • Structure-Elucidating Total Synthesis of the (Polyenoyl)tetramic Acid Militarinone C
    作者:Christian Drescher、Morris Keller、Olivier Potterat、Matthias Hamburger、Reinhard Brückner

    日期:2020.4.3
    The (polyenoyl)tetramic acid militarinone C (1) heads a family of seven members. Before our work, the configuration of C-5 was unknown whereas the configurations of C-8′ and C-10′ were either (R,R) or (S,S). We synthesized the four stereoisomers of constitution 1, which conform with these insights. This included cross-coupling both enantiomers of the western building block (8) with both enantiomers
    (多烯酰基)四甲酸米利替农C(1)领导着一个由七个成员组成的家庭。在我们进行工作之前,C-5的构型是未知的,而C-8'和C-10'的构型是(R,R)或(S,S)。我们合成了构成1的四个立体异构体,它们与这些见解相符。这包括将西部结构单元(8)的两个对映体与东部结构单元(9)的两个对映体交叉偶联。产生的1个异构体的比旋光表明,天然1的构型与偶联配偶体(S)-图8和(R,R)-9。通过将天然1降解为酒精35并通过与合成(R,R)-35证明其构型同一性,证实了这一结论。

    relative stereochemistry of the β-keto carboxylic acid chain of the analogous alkaloid hirsutellomycin was determined in a stepwise manner. The C4′–C6′ syn relationships were predicted by comparing the NMR data of the corresponding ester fragments with that of hirsutellomycin. The relative stereochemistry of the whole molecule, including the epimerizable C2′ stereocenter, was determined by introduction
    通过半合成确定C 2对称的表二代二酮哌嗪生物碱SCH 64874的结构。通过比较四个可能的非对映异构的β-羟基羧酸片段与SCH 64874的NMR数据,可以确定具有三个手性中心的β-羟基羧酸链的相对立体化学。两种对映体的β-羟基羧酸揭示了SCH 64874的相对立体化学。以逐步方式确定了类似生物碱hirsutellomycin的β-酮羧酸链的相对立体化学。该C4'-C6' SYN通过将相应酯片段的NMR数据与hirsutellomycin的NMR数据进行比较,可以预测二者之间的相关性。整个分子的相对立体化学,包括可差向异构的C2'立体中心,是通过将四个可能的侧链引入双脱基二(甲基)脱乙酰基花生四烯酸核心来确定的。我们发现,C2'的立体化学与受核心结构影响的热力学稳定形式的立体化学趋同。

    pseudoephedrine as a practical chiral auxiliary for asymmetric synthesis is described in full. Both enantiomers of pseudoephedrine are inexpensive commodity chemicals and can be N-acylated in high yields to form tertiary amides. In the presence of lithium chloride, the enolates of the corresponding pseudoephedrine amides undergo highly diastereoselective alkylations with a wide range of alkyl halides to
    麻黄碱作为不对称合成的实用手性助剂的使用进行了全面的描述。伪麻黄碱的两种对映异构体都是廉价的商品化学品,可以高产率进行 N-酰化以形成叔酰胺。在氯化锂的存在下,相应的伪麻黄碱酰胺的烯醇化物与多种卤代烷发生高度非对映选择性的烷基化反应,以高产率得到 α-取代产物。然后,这些产品可以在一次操作中转化为高度对映异构的羧酸、醇、醛和酮。

    The research addresses the reaction of terminal alkenes and propene with AlR3 (R = Me, Et) in the presence of chiral Zr complexes, rac-[Y(η5-C9H10)2]ZrCl2 (Y = C2H4, SiMe2) or (NMI)2ZrCl2 (NMI- η5–neomenthylindenyl), and methylaluminoxane. The effect of reaction conditions, catalyst and trialkylalane structure on the substrate conversion and the reaction chemo- and stereoselectivity has been studied

  • Structural Elucidation of Twelve Novel Esters Composed of Five Fatty Acids and Three New Branched Alcohols Together with Four Monoterpenoids from Sancassania shanghaiensis (Acari: Acaridae)
    作者:Tomoyo SAKATA、Kimiko OKABE、Yasumasa KUWAHARA
    DOI:10.1271/bbb.65.919
    日期:2001.1
    A total of 12 novel esters and four monoterpenoids (rosefuran, (2R,3R)-epoxyneral, and α- and β-acaridials) were detected by GC/MS analyses as the opisthonotal gland components of Sancassania shanghaiensis. The acidic fraction after hydrolysis was composed of five common fatty acids (palmitic, stearic, oleic, linoleic and arachidic acid), while the alcoholic fraction consisted of two major components (C6 and C8 alcohols with branched methyls), together with a trace amount of C9 alcohol. The Two major alcohols were identified as new alcohols [(S)-2-methylpentanol and (2S,4S)-2,4-dimethylhexanol] by comparing the physico-chemical data of their 3,5-dinitrobenzoates with those of regio-selectively synthesized alcohols. The C9 alcohol was suggested as (2S,4S)-2,4-dimethylheptanol, based on a structural and biogenetic analogy to the C6 and C8 alcohols. Five of the compounds were each identified by GC to be (S)-2-methylpentyl esters from five fatty acids, and the other five components likewise as (2S,4S)-2,4-dimethylhexyl esters. The remaining two were suggested as (2S,4S)-2,4-dimethylheptyl Stearate and linolate.
    GC/MS分析在Sancassania shanghaiensis的抱粉腺成分中检测到总共12种新型酯和4种单萜(玫瑰呋喃、(2R,3R)-环氧橙花醇以及α-和β-刺檗二醇)。经过解后的酸性部分由5种常见脂肪酸棕榈酸硬脂酸油酸亚油酸花生酸)组成,而醇性部分则主要由两种成分(带有支链甲基的C6和C8醇)组成,同时含有微量的C9醇。通过比较其3,5-二硝基苯甲酸酯的物理化学数据与选择性合成醇的数据,确认这两种主要醇为新型醇[(S)-2-甲基戊醇和(2S,4S)-2,4-二甲基己醇]。根据结构和生物学上的相似性,C9醇被推测为(2S,4S)-2,4-二甲基庚醇。通过GC鉴定,五种化合物分别为五种脂肪酸的(S)-2-甲基戊酯,另外五种成分同样为(2S,4S)-2,4-二甲基己酯。剩下的两种被推测为(2S,4S)-2,4-二甲基庚酯的硬脂酸酯和亚油酸酯。
