  • Conjugate addition of (trimethylstannyl)copper reagents to α,β-acetylenic N,N-dimethylamides. Trapping of the intermediates with electrophiles

    A study of the reaction of Me3SnCu·.Me2S (1) and [Me3SnCuSPh]Li (2) with α,β - acetylenic N,N-dimethylamides 3 shows (a) that the overall process can be controlled experimentally so as to produce either N,N-dimethyl ()-(4) or ()-3-trimethylstannyl-2-alkenamides (5), (b) that the initially formed intermediate derived from interaction of 2 and 3 is significantly more stable than that obtained by reaction
    对Me 3 SnCu·.Me 2 S(1)和[Me 3 SnCuSPh] Li(2)与α,β-炔属N,N-二甲基酰胺3反应的研究表明(a)可以控制整个过程实验上产生N,N-二甲基()-(4)或()-3-三甲基锡烷基-2-烯酰胺(5),(b)由2和3的相互作用产生的最初形成的中间体明显更多与通过2与α,β-炔属酸酯的反应所获得的中间体相比,该化合物具有更稳定的稳定性,并且(c)通过用1处理3所产生的中间体可以被质子以外的亲电试剂捕获。
  • Convenient synthesis of alkyl (Z)- and (E)-2,3-bis(trimethylstannyl)alk-2-enoates and N,N-dimethyl (E)-2,3-bis(trimethylstannyl)alk-2-enamides

    Palladium(0)-catalysed addition of (Me3Sn)2 to the α,β-acetylenic esters (1a–n) and amides (4a–d) provides the (Z)-2,3-bis(trimethylstannyl)alk-2-enoates (2a–n) and the (E)-2,3-bis(trimethylstannyl)alk-2-enamides (6a–d), respectively; thermolysis of (2a–h) transforms these substances into the corresponding (E)-isomers (3a–h).

  • Reactions of phenyldimethylsilyllithium with β-<i>N</i>,<i>N</i>-dimethylaminoenones: A convenient synthesis of β-dimethyl(phenyl)silylacrylic acid and its derivatives
    作者:Ian Fleming、Elena Marangon、Chiara Roni、Matthew G Russell、Sandra Taliansky Chamudis

    Phenyldimethylsilyllithium reacted with 5,5-dimethyl-3-(N,N-dimethylamino)cyclohex-2-enone (7), 3-(E)-N,N-dimethylaminopropenal (11), and 4-N,N-dimethylaminobut-3-en-2-one (13) to give the corresponding β-silyl-α,β-unsaturated carbonyl compounds 8, 12, and 14, in which the dimethylamino group has been displaced by the phenyldimethylsilyl group. Phenyldimethylsilyllithium reacted with ethyl β-N,N-dimethylaminopropenoate (15) by conjugate addition, but, in contrast to the ketones 7 and 13 and the aldehyde 11, the intermediate enolate 16 was C-protonated in the aqueous work-up to give ethyl 3-N,N-dimethylamino-3-dimethyl(phenyl)silylpropanoate (17). When the enolate 16 was instead given a mysteriously brief treatment with methyl iodide before work-up, the product was ethyl 3-(E)-dimethy(phenyl)silylpropenoate (18). Phenyllithium and methyllithium also added conjugatively to ethyl β-N,N-dimethylaminoacrylate (15) but, in contrast to the silyl case, the intermediate enolate 22 reacted unexceptionally with methyl iodide to give the products 25 and 26 of stereoselective C-methylation. This synthesis of the ester 18 was used to synthesize the Oppolzer sultam derivative 30.Key words: conjugate addition, elimination, substitution, silyllithium, silylenone.

    苯基二甲基硅基锂与5,5-二甲基-3-(N,N-二甲基氨基)环己-2-烯酮(7)、3-(E)-N,N-二甲基氨基丙烯醛(11)和4-N,N-二甲基氨基丁-3-烯-2-酮(13)反应,得到相应的β-硅基-α,β-不饱和羰基化合物8、12和14,其中二甲基氨基团被苯基二甲基硅基团取代。苯基二甲基硅基锂与乙基β-N,N-二甲基氨基丙烯酸酯(15)通过共轭加成发生反应,但与酮类7和13以及醛11不同,中间体烯醇酸酯16在水工作处理中被C-质子化,生成乙基3-N,N-二甲基氨基-3-二甲基(苯基)硅基丙酸酯(17)。当烯醇酸酯16在工作处理前突然用碘甲烷短暂处理时,产物为乙基3-(E)-二甲基(苯基)硅基丙烯酸酯(18)。苯基锂和甲基锂也与乙基β-N,N-二甲基氨基丙烯酸酯(15)发生共轭加成,但与硅基情况不同,中间体烯醇酸酯22与碘甲烷反应,产生立体选择性的C-甲基化产物25和26。这种合成酯18的方法被用来合成Oppolzer磺胺衍生物30。关键词:共轭加成,消除,取代,硅基锂,硅烯酮。
