  • Palladium-catalysed regio- and stereoselective arylative substitution of γ,δ-epoxy-α,β-unsaturated esters and amides by sodium tetraaryl borates
    作者:Yasemin Bilgi、Melih Kuş、Levent Artok
    DOI:10.1039/d0ob01226b
    日期:——
    Palladium-catalysed reactions of γ,δ-epoxy-α,β-unsaturated esters and amides with NaBAr4 reagents proceeded regio- and stereoselectively, producing allylic homoallyl alcohols with aryl-substituents in the allylic position for a wide range of substrates. AsPh3 was found to be a competent ligand for the arylation reaction, whereas phosphine ligand/Lewis acidic organoboron combinations favoured the substitution
    钯催化的 γ,δ-环氧-α,β-不饱和酯和酰胺与 NaBAr 4试剂的反应以区域选择性和立体选择性进行,产生在烯丙基位置具有芳基取代基的烯丙基高烯丙基醇,适用于各种底物。AsPh 3被发现是芳基化反应的有效配体,而膦配体/Lewis 酸性有机硼组合有利于氧亲核试剂(例如H 2 O、ROH)的取代反应。
  • Isomerization of Electron-Poor Alkynes to the Corresponding (E,E)-1,3-Dienes Using a Bifunctional Polymeric Catalyst Bearing Triphenylphosphine and Phenol Groups

    日期:2010.10
    The use of a bifunctional non-cross-linked polystyrene bearing both phosphme and phenol groups tor the organocatalytic isomerization of alkynes bearing electron-withdrawing ester substituents to afford the corresponding (E,E)-dienes in excellent yield and stereoselectivity is described. When polystyrene functionalized with only phosphine groups was used as the catalyst, either low or no yield of the
    描述了使用带有膦基和苯酚基团的双官能非交联聚苯乙烯对带有吸电子酯取代基的炔烃进行有机催化异构化,以优异的产率和立体选择性提供相应的 (E,E)-二烯。当仅用膦基团官能化的聚苯乙烯用作催化剂时,所需产物的收率低或没有收率。因此,双功能聚苯乙烯催化剂的两个官能团对于有效催化的发生都是必不可少的。这种双功能聚合物催化剂还用于从相应的炔烃合成 (E,E,E)-三烯和 (E,E)-二烯取代的 2(H)-吡喃-2-酮。

  • Stereoselective Synthesis of Conjugated 2,4-Alkadienoates via the Palladium-Catalyzed Cross-Coupling of 1-Alkenylboronates with 3-Bromo-2-alkenoates
    作者:Teiji Yanagi、Takayuki Oh-e、Norio Miyaura、Akira Suzuki

    (2E,4E)-, (2Z,4E)-, and (2E,4Z)-2,4-Alkadienoates can be synthesized in high yields by the cross-coupling of ethyl (E)-3-bromoacrylate, methyl (E)-3-bromo-2-methylpropenoate, ethyl (Z)-3-bromocrotonate,1-bromo-2-(ethoxycarbonyl)cyclohexene, and 4-bromocoumarin with 2-[(E)-1-alkenyl]-1,3,2-benzodioxaboroles or diisopropyl (Z)-1-hexenylboronate in the presence of 3 mol% of Pd(OAc)2, 6 mol% of PPh3, and 2 equivalents of Na2CO3 or K2CO3 in alcoholic solvents while retaining the original configuration of the double bonds in β-bromo esters and 1-alkenylboronates. Although the coupling reaction with 1-hexenylboronate with (Z)-3-bromoacrylate gave a mixture of ethyl (2Z,4E)- and (2E,4E)-nonadienoates in a ratio of 63 : 37, it was found that the use of bis(diphenylphosphino)ferrocene as a ligand of palladium brought about the stereoselective coupling under mild conditions.
    (2E,4E)-、(2Z,4E)- 和 (2E,4Z)-2,4-烷二烯酸酯可以通过乙基(E)-3-溴丙烯酸酯、甲基(E)-3-溴-2-甲基丙烯酸酯、乙基(Z)-3-溴丙烯酸酯、1-溴-2-(乙氧羰基)环己烯和4-溴香豆素与2-[(E)-1-烯基]-1,3,2-苯并二氧硼烷或二异丙基(Z)-1-己烯基硼酸酯在3摩尔%的Pd(OAc)2、6摩尔%的PPh3和2当量的Na2CO3或K2CO3的存在下,在醇溶剂中交叉耦合合成,且保持β-溴酯和1-烯基硼酸酯中双键的原始构型。尽管1-己烯基硼酸酯与(Z)-3-溴丙烯酸酯的耦合反应生成了63:37比率的乙基(2Z,4E)-和(2E,4E)-九烯酸酯的混合物,但发现使用双(苯基磷)铁烯作为钯的配体在温和条件下能够实现立体选择性耦合。
