    microwave‐irradiated alcohol‐protecting strategy based on gold catalysis utilizing benzyl alcohol, tert‐butyl alcohol and triphenylmethanol as alkylating reagents has been developed. This protecting strategy has wide functional group tolerance with satisfactory yields for the majority of the selected alcohols. The mechanism of this transformation was probed with oxygen‐18 isotope labelled alcohols assisted by

    The spirocyclic part consisting of an α-acylated tetronic acid and a multisubstituted cyclohexene embedded in versipelostatin, a novel GRP78/Bip molecular chaperone downregulator, has been synthesized in enantiomerically pure form. The asymmetric synthesis of the targeted spiro[4.5]-1-oxa-7-decen-2,4-dione derivative was characterized by (1) stereoselective allylation at the α-carbon of methylmalonate diester, in which one carboxylic acid was esterified with a D-glucose-derived chiral template, (2) construction of the tetrasubstituted cyclohexenone substructure by high-yielding ring-closing metathesis and (3) stereoselective construction of the spirocyclic tetronic acid part starting from the cyclohexenone obtained as the ring-closing metathesis product.

    作者:Fenja L. Duecker、Robert C. Heinze、Philipp Heretsch
    DOI:10.1021/jacs.9b12899
    日期:2020.1.8
    reconstruction approach to structurally unique 13(14→8),14(8→7)diabeo-steroid swinhoeisterol A was developed. The conversion of an ergostane skeleton proceeded through the intermediacy of a 13(14→8)abeo-framework as present in the dankasterone and periconiastone family of natural products and features a β scission of a 14-alkoxy radical with concomitant generation of the C8-C13 bond. From this intermediate
    开发了一种用于结构独特的 13(14→8),14(8→7)diabeo-steroid swinhoeisterol A 的可切换自由基框架重建方法。麦角甾烷骨架的转化是通过 13(14→8)abeo 框架的中间体进行的,这些框架存在于天然产物丹卡甾酮和周石酮家族中,其特征是 14-烷氧基自由基的 β 断裂伴随 C8- C13 键。从这个中间体开始,根据所采用的条件,级联继续进行 Dowd-Beckwith 重排,并导致形成天然产物 swinhoeisterol 类的 13(14→8),14(8→7)diabeo 框架. 然后,这些框架的合成允许有效地获得 swinhoeisterol A (1)、dankasterone A (Δ4-2)、dankasterone B (2) 和 periconiastone A (3)。

    作者:Christian A. Citron、Corina Junker、Barbara Schulz、Jeroen S. Dickschat
    DOI:10.1002/anie.201402290
    日期:2014.4.22
    largely unknown secondary metabolism of the plant pathogenic fungus Hymenoscyphus pseudoalbidus was investigated by use of the CLSA method. A set of volatile lactones was identified by GC/MS. The lactones were synthesized and used in bioassays in which one of the compounds was found to be a strong germination inhibitor for ash seeds, causing necroses in the plant tissue.

  • Pyrrolizidine Alkaloids. The Synthesis and Absolute Configuration of All Stereoisomers of Monocrotalic Acid
    作者:Takashi Matsumoto、Makoto Takahashi、Yutaka Kashihara
    DOI:10.1246/bcsj.52.3329
    日期:1979.11
    All stereoisomers (3a, b–6a, b) of monocrotalic acid have been synthesized. Methylation of (±)-cis-2,3,4-trimethyl-2-pentenedioic acid with diazomethane followed by cis-hydroxylation with potassium permanganate afforded two epimeric γ-lactone esters in a ratio of ca. 1:5. These esters were then hydrolyzed with dilute hydrochloric acid to the corresponding acids, (±)-3 and racemic monocrotalic acid
    已合成了百合酸的所有立体异构体(3a、b-6a、b)。(±)-cis-2,3,4-trimethyl-2-pentenedioic 酸用重氮甲烷甲基化,然后用高锰酸钾顺式羟基化,得到两种差向异构 γ-内酯酯,比例约为 1:5。然后用稀盐酸将这些酯水解成相应的酸,(±)-3 和外消旋单巴豆酸 (4)。(±)-3 与 brucine 的光学分辨率提供 3a (2R,3R,4S) 和 3b (2S,3S,4R)。外消旋的单巴豆酸也通过马铃薯碱分解,得到天然的单巴豆酸(4a:2R、3R、4R)及其对映异构体(4b:2S、3S、4S)。随后,(±)-trans-2,3,4-trimethyl-2-pentenedioic acid 用辛可尼丁拆分,得到 8a 和 8b,通过与已知的 (R)-(-)-2-苯基丙酸相关联,其立体化学分别指定为 S- 和 R- 构型。8a 甲基化,然后顺式羟基化和水解得到
