  • Yne-Allenes from 1-Bromoallenes and Trimethylstannylacetylenes via Palladium-Mediated C–C Coupling Reactions
    作者:Rolf W. Saalfrank、Martin Haubner、Christian Deutscher、Walter Bauer
    DOI:10.1002/(sici)1099-0690(199909)1999:9<2367::aid-ejoc2367>3.0.co;2-9
    日期:1999.9
    provided a convenient route for the synthesis of the conjugated yne-allenes 7 or the diastereomeric yne-diallenes, meso-9 and (R,R)/(S,S)-9. Analogously to 7, the phosphorylyne-allenes 14 were also prepared under Stille conditions, starting from the phosphorylallenes 12 and propargylstannane 6a. Alternatively, yne-allenes 17 and 18 were obtained from hexadiynol 16 with orthoester 2b or diethoxychlorophosphane
    丙炔 3 与甲炔基炔烃 6 或二甲炔基炔烃 8 的斯蒂勒交叉偶联为合成共轭炔-丙炔-7 或非对映异构炔-二丙炔、meso-9 和 (R,R)/(S, S)-9。与 7 类似,酰炔-丙二烯 14 也在斯蒂勒条件下制备,从丙二烯 12 和炔丙基烷 6a 开始。或者,炔-丙二烯17和18是通过[3.3]-和[2.3]-sigmatropic重排从己二炔醇16与原酸酯2b或二乙氧基膦13a获得的。
  • Cation-Mediated, Substituent-Controlled, C<sup>2</sup>−C<sup>7</sup> Cycloaromatization of an Enyne−Allene
    作者:Rolf W. Saalfrank、Martin Haubner、Christian Deutscher、Walter Bauer、Timothy Clark
    DOI:10.1021/jo982340x
    日期:1999.8.1
    Reaction of(2-bromophenylethynyl)trimethylsilane 1 with trimethyl berate yielded the alkynearyl-boronic acid 2, which was coupled in situ with the bromoallenes 3 to give enyne-allenes 4. The intermediates 4 underwent a spontaneous cation-mediated C-2-C-7 cycloaromatization with a concomitant 1,2-shift of the trimethylsilyl group to give the naphthalene derivatives 5. Besides 5, yne-allenes 10 were isolated by chromatography of the crude reaction products. A key step in the formation of 10 is the hydrolysis of the aryl boronic acid 2, which led to phenylethynyltrimethylsilane 8. Under the reaction conditions used, the TMS group of 8 was subsequently removed to give phenylacetylene 9, which further reacted with the bromoallenes 3 to furnish the yne-allenes 10.
