    Synthesis of indenothiophenone derivatives by cycloaromatization of non-conjugated thienyl tetraynes
    摘要:
    Non-conjugated thienyl tetrayne derivatives 1-3 are prepared as novel building block for the construction of indenothiophenone derivatives. Oxidation of 1-3, followed by cycloaromatization of the corresponding ketone derivatives 13-15 proceeds smoothly to afford indenothiophenone derivatives 16-21 in good yields. (C) 2005 Elsevier Ltd.

    Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 4. Stepwise construction of terminal 1, 3-diynes, conjugated diacetylenic esters and a triacetylenic ester
    摘要:
    Thirteen examples of stabilised alkynoyl ylides 6 have been prepared and are found, upon flash vacuum pyrolysis (FVP) at 500 degrees C, to undergo extrusion of Ph(3)PO to give the diacetylenic esters 7 in moderate yield. At 750 degrees C the same ylides afforded terminal 1.3-diynes 8 although often in poor yield. For R = 2-MeSC(6)H(4) both 7 and 8 undergo secondary loss of Me(.) and cyclisation to give 2-alkynylbenzothiophene derivatives 9 and 10 in low yield. The first example of an alkadiynoyl ylide 11 has been prepared and is converted by FVP at 500 degrees C into the triacetylenic ester 12.

    日期:2018.11.2
    exclusively 3-borylated thiophene derivatives is reported. The commercially available B-chlorocatecholborane reagent (ClBcat) acts as a carbophilic Lewis acid to activate the alkyne in readily synthesized (Z)-organylthioenyne substrates. This boron-induced activation initiates the formal thioboration and subsequent sulfur dealkylation, leading to the formation of 3-borylated thiophenes in good yields. The
    据报道,一种简单的,不受区域控制的,无过渡属的方法仅可访问3-化的噻吩生物。市售的B-邻苯二甲硼烷试剂(ClBcat)用作亲碳的路易斯酸,以活化易于合成的(Z)-有机基代炔炔底物中的炔烃诱导的活化引发了正式的化和随后的脱烷基化,从而以高收率形成了3-化的噻吩。所得的噻吩可分离为硼酸酯(Bpin)和酰胺(Bdan)。这些化的产物适合于各种下游官能化反应,即通过交叉偶联,叠氮化,化和CH活化形成CC键。
  • Cyclobutene vs 1,3-Diene Formation in the Gold-Catalyzed Reaction of Alkynes with Alkenes: The Complete Mechanistic Picture

    The intermolecular gold(I)-catalyzed reaction between arylalkynes and alkenes leads to cyclobutenes by a [2 + 2] cycloaddition, which takes place stepwise, first by formation of cyclopropyl gold(I) carbenes, followed by a ring expansion. However, 1,3-butadienes are also formed in the case of ortho-substituted arylalkynes by a metathesis-type process. The corresponding reaction of alkenes with aryl-1
    芳基炔烃与烯烃之间的分子间(I)催化反应通过[2 + 2]环加成反应逐步生成环丁烯,该过程逐步进行,首先形成环丙基(I)卡宾,然后进行环扩环。但是,在邻位的情况下也会形成1,3-丁二烯复分解型方法取代了芳基炔烃。烯基与芳基炔烃对应的烯烃与芳基-1,3-丁二炔的相应反应仅产生环丁烯。在密度泛函理论计算的基础上,提出了炔烃与烯烃的(I)催化反应的综合机理,表明生成环丁烯或二烯的两条途径的能量非常接近。关键中间体是环丙基(I)卡宾,它们是通过逆向布赫纳反应从立体定义的1a,7b-二氢-1 H-环丙烷[ a ]独立生成的。

    A direct catalytic enantioselective alkynylation reaction of trifluoropyruvates with terminal 1,3-diynes was achieved by using C2-symmetric NCN pincer rhodium (III) complexes with bis(imidazolinyl)phenyl ligands. This protocol is effective for enantioselective synthesis of optically active trifluoromethylated tertiary alcohols with the diyne moiety. A variety of electronically and structurally diverse
