  • Enantiomeric β-angelica lactone epoxides: their syntheses from suitable chiral precursors and their use in the preparation of blastmycinone
    作者:Rosa M. Ortuño、Daniel Alonso、Jaume Cardellach、Josep Font

    日期:1987.1
    Syntheses of (S)-β-angelica lactone from L-tartaric acid and (R)-γ-hydroxy-methyl-γ-butyrolactone, 5, are reported. Alternative routes to prepare 5 from S- and R-glutamic acids and D-ribonolactone, respectively, are also presented. Epoxides derived from (R)- and (S)-β-angelica lactones have been obtained and their use in the synthesis of both (+)- and (-)-blastmycinone, 24, has been established.

  • A Four-Step Route from Aldehydes to C<sub>2</sub>-Elongated Enantiomerically Pure <i>α</i>,<i>β</i>-Unsaturated <i>γ</i>-Hydroxy Esters
    作者:Christian Harcken、Reinhard Brückner
    DOI:10.1055/s-2001-13372
    日期:——
    Asymmetric dihydroxylation of β,γ-unsaturated esters 4 provided β-hydroxy-γ-lactones 3 or ent-3. Methanolysis acetonide formation and LDA-mediated fragmentation of the resulting esters 5/ent-5 furnished the γ-chiral acrylates 6/ent-6 containing disubstituted C=C bonds (93-99% ee). Also, β-hydroxy-γ-lactones ent-3 a and 3 b were α-butylated and α-brominated, respectively, prior to methanolysis, acetonide formation, and fragmentation which led to the γ-chiral acrylates 9 and 12 with trisubstituted C=C bonds (94 and 95% ee, respectively).
    β,γ-不饱和酯4 的不对称二羟基化提供β-羟基-γ-内酯3 或ent-3。甲醇分解丙酮化物的形成和所得酯5/ent-5 的LDA 介导的断裂提供了含有双取代C=C 键(93-99% ee)的γ-手性丙烯酸酯6/ent-6。此外,β-羟基-γ-内酯 ent-3 a 和 3 b 分别在甲醇解、丙酮化物形成和裂解之前进行 α-丁基化和 α-溴化,从而产生 γ-手性丙烯酸酯 9 和 12三取代的 C=C 键(分别为 94% 和 95% ee)。

    日期:2014.8
    A straightforward and convergent total synthesis of (+)‐antimycin A3b is reported. Four fragments were assembled on a solid support and the fully functionalized seco acid was cyclized in the solution phase. This synthetic route minimized the number of manipulations in the solution phase and is useful for a combinatorial library synthesis.

  • Total Syntheses of (−)-Grandinolide and (−)-Sapranthin by the Sharpless Asymmetric Dihydroxylation of Methyltrans-3-Pentenoate: Elucidation of the Stereostructure of (−)-Sapranthin

    Methyl trans-3-pentenoate (7) was converted into the cis-substituted gamma-lactone 8 in a single step with 78 % ee. The derived enolate dilithio-8 was alkylated trans-selectively with primary iodoalkanes. with 1-iodobutane dilithio-8 afforded, after esterification with isovaleroyl chloride, the epi-blast mycinone 9, Dilithio-8 gave (-)-grandinolide (11) with 1-iodo-19-phenylnonadecane (20), A third trans-selective alkylation of dilithio-8 was undertaken with 16-iodo-1.5-hexadecadiene-7,9-diyne (21). This gave the gamma-lactone 12. which had the published relative configuration of (-)-sapranthin but different spectroscopic data, When the OH group of lactone 8 was inverted (to hydroxylactone 40) and the derived enolate dilithio-40 alkylated with iodide 21, lactone 41 resulted, Its H-1 and C-13 NMR spectra and the sign and value of optical rotation coincide with the data of natural sapranthin, These findings establish that (-)-sapranthin possesses the relative and absolute configuration of stereoformula 41. The synthesis of iodide 21 was performed via the dienoic carboxylic ester trans-23 which stemmed from the Claisen-Ireland rearrangement (27 --> 28/29)/esterification (28/29 --> 26)/Cope rearrangement (26 - 23) sequence shown in Scheme 5.
