  • An efficient synthesis of 2,3,5-trisubstituted furans from α,β-unsaturated ketones
    作者:Catherine D. Brown、J.Michael Chong、Lixin Shen
    DOI:10.1016/s0040-4020(99)00898-4
    日期:1999.12
    A simple, regioselective synthesis of 2,3,5-trisubstituted furans is described. Conjugate addition of alkynylboronates to α,β-unsaturated ketones, followed by acid-catalyzed cyclization of the resulting γ-alkynyl ketones affords trisubstituted furans in 31–97% overall yields.
    描述了2,3,5-三取代的呋喃的简单的区域选择性合成。将炔基硼酸酯加成到α,β-不饱和酮上,然后酸催化环化所得的γ-炔基酮,可得到三取代呋喃,总产率为31-97%。
  • An efficient palladium-catalyzed coupling reaction of lithium alkynyltriisopropoxyborates with acid chlorides: a new access to synthesis of conjugated ynones
    作者:Chang Ho Oh、V. Raghava Reddy
    DOI:10.1016/j.tetlet.2004.09.114
    日期:2004.11
    An efficient palladium-catalyzed protocol for the synthesis of ynones from lithium alkynyltriisopropoxyborates with acid chlorides under mild neutral conditions.
    在温和的中性条件下,由炔基三异丙氧基硼酸锂与酰氯合成炔酮的有效钯催化方案。
  • Palladium-Catalyzed Diastereoselective Coupling of Propargylic Oxiranes with Terminal Alkynes
    作者:Masahiro Yoshida、Maiko Hayashi、Kozo Shishido
    DOI:10.1021/ol070224n
    日期:2007.4.1
    A diastereoselective coupling of propargylic oxiranes with terminal alkynes has been developed with use of a palladium catalyst. The stereochemistries of the resulting 4-alkynyl-substituted 2,3-allenols have been altered depending on the palladium catalyst. An optically active anti-substituted allene was synthesized from the reaction of an enantiomerically enriched propargylic oxirane without loss of chirality.
  • Suzuki−Miyaura Coupling of Alkynylboronic Esters Generated in Situ from Acetylenic Derivatives
    作者:Anne-Sophie Castanet、Françoise Colobert、Thierry Schlama
    DOI:10.1021/ol006439d
    日期:2000.11.1
    A new effective Suzuki-Miyaura coupling reaction between alkynylboronic esters (generated in situ from acetylenic derivatives) and arylbromides or vinylbromides is reported.
    报道了炔基硼酸酯(从炔属衍生物原位产生)与芳基溴化物或乙烯基溴化物之间的新的有效的Suzuki-Miyaura偶联反应。
  • Pt(0)-Catalyzed Alkynylation of Aryl Iodides with Lithium Alkynyltriisopropoxy Borates
    作者:Chang Ho Oh、V. Raghava Reddy
    DOI:10.1055/s-2004-832819
    日期:——
    An efficient cross coupling reaction of various lithium alkynyltriiospropoxyborates with a wide array of aryl iodides was catalyzed by Pt(PPh3)4-CuI in DMF as a solvent. These cross coupling reactions are general and permit the new sp-sp2 carbon-carbon bond formation.
    一种高效的交叉耦合反应,将各种锂炔基三异丙苯氧基硼酸酯与多种芳基碘化物在DMF溶剂中,以Pt(PPh3)4-CuI为催化剂进行。这些交叉耦合反应具有普遍性,能够形成新的sp-sp2碳碳键。
