  • From Amino Acids To Dihydrofurans: Functionalized Allenes in Modern Organic Synthesis
    作者:Norbert Krause、Anja Hoffmann-Röder、Johannes Canisius
    DOI:10.1055/s-2002-33707
    日期:——
    In this account, recent accomplishments in the field of target-oriented synthesis involving allenes are summarized. Allenic α-amino acid derivatives 9, which are of interest as possible vitamin B 6 decarboxylase inhibitors, were prepared by 1,6-addition of the cyano-Gilman reagent t-Bu 2 CuLi-LiCN to 2-amino-substituted enynoates 8. and selective deprotection at either the amino or the ester group
    本文总结了最近在涉及丙二烯的靶向合成领域取得的成就。通过将氰基-吉尔曼试剂 t-Bu 2 CuLi-LiCN 与 2-氨基取代的烯醇酸酯 8 进行 1,6-加成,制备了可能作为维生素 B 6 脱羧酶抑制剂的艾伦族 α-氨基酸衍生物 9。并实现了氨基或酯基的选择性脱保护。2,5-二氢呋喃18由相应的α-羟基丙二烯环化得到;对于这一步,开发了新的方法(用氯化氢气体或酸性离子交换树脂处理;金(III)-氯化物催化)。2-羟基-3,4-二烯酸 14 是通过用二甲基二环氧乙烷 (DMDO) 对由 3,4-二烯酸 12 形成的钛烯醇化物进行非对映选择性氧化获得的,
  • Efficient Synthesis of 2-Hydroxy-3,4-dienoates by Oxidation of Zirconium­allenyl Enolates with Dimethyldioxirane
    作者:Norbert Krause、Anja Hoffmann-Röder
    DOI:10.1055/s-2006-942409
    日期:2006.7
    The α-hydroxylation of zirconiumallenyl enolates, obtained from β-allenic esters by deprotonation with LDA or LiN(SiMe3)2 and transmetalation with Cp2ZrCl2, with dimethyldioxirane (DMDO) selectively affords 2-hydroxy-3,4-dienoates. The oxidation proceeds usually with high yield and substrate conversion and tolerates even sensitive or unreactive substrates.
    使用二甲基二氧杂环丙烷(DMDO)对由β-丙二烯酯通过LDA或LiN(SiMe3)2去质子化及与Cp2ZrCl2转移金属化得到的锆丙二烯烯醇酸盐进行α-羟基化反应,可选择性地生成2-羟基-3,4-二烯酸酯。该氧化反应通常具有高产率和底物转化率,甚至能容忍敏感或不活泼的底物。
  • Ruthenium-Catalyzed Flash Oxidation of Allenes to α,α'-Dihydroxyketones
    作者:Michael Laux、Norbert Krause
    DOI:10.1055/s-1997-5759
    日期:1997.7
    The ruthenium-catalyzed flash oxidation of β-allenic esters 1 furnishes α,α'-dihydroxyketones 2 in 24-72% yield. In the case of the chiral allene 1e, the oxidation proceeds with good diastereoselectivity (88% de), i.e. with efficient axis to center chirality transfer. The flash oxidation can also be used for the synthesis of corticosteroids, as exemplified by the transformation of allenic steroid 4 into dihydroxyketone 5.
    钌催化的β-烯丙基酯的闪蒸氧化反应1可生成α,α'-二羟基酮2,产率可达24-72%。对于手性烯丙基1e,氧化反应具有良好的立体选择性(88% de),即具有高效的轴向中心手性转移。闪蒸氧化也可用于皮质类固醇的合成,例如烯丙基类固醇4转化为二羟基酮5。
