  • Reaction of β-halo α, β-unsaturated ketones with cuprate reagents. Efficient syntheses of β, β-dialkyl ketones and β-alkyl α,β-unsaturated ketones. A synthesis of (<i>Z</i>)-jasmone
    作者:Edward Piers、Kin Fai Cheng、Isao Nagakura
    DOI:10.1139/v82-185
    日期:1982.5.15

    Treatment of the 3-halo-2-cyclohexen-1-ones 11–15 and 17 with an excess of lithium dimethylcuprate provided good to excellent yields of the corresponding 3,3-dimethylcyclohexanones 21–24. Similar reactions involving the β-bromo cyclopentenones 19 and 20 stopped at the monoaddition stage, producing the cyclopentenones 40 and 43. Reaction of the β-bromo cyclohexenones 12 and 15 with 1.1 equiv. of lithium dimethylcuprate did not effect clean conversion of these substrates into the corresponding 3-methyl-2-cyclohexen-1-ones. When a series of β-bromo enones 12, 14–19 were allowed to react with the lithium (phenylthio)(alkyl)cuprates 44–47, the corresponding β-alkyl enones were, in general, produced cleanly and efficiently. However, reaction of 3-bromo-2-methyl-2-cyclopenten-1-one (19) with the cuprate reagent 44 gave mainly the β-phenylthio enone 49. This undesired result could be avoided by employing, in the place of 19, the β-iodo cyclopentenone 50, which reacted smoothly with 44 to give a high yield of 2,3-dimefhyl-2-cyclopenten-1-one (40). Reaction of 3-bromo-2-cyclohexen-1-one (14) with 3 equiv. of the mixed vinylcuprate reagent 48 gave 3-(3-butenyl)-2-cyclohexen-1-one (32). Alkylation of 1,3-cyclopentanedione with (Z)-1-chloro-2-pentene afforded compound 51, which was converted into the β-bromo enone 52. Treatment of the latter substance with lithium dimethylcuprate provided (Z)-jasmone (53).

    将3-卤代-2-环己烯-1-酮11-15和17与过量的二甲基溴化锂处理,得到相应的3,3-二甲基环己酮21-24,收率良好至优良。涉及β-溴代环戊烯酮19和20的类似反应在单加成阶段停止,产生环戊烯酮40和43。β-溴代环己烯酮12和15与1.1当量的二甲基溴化锂反应未对这些底物进行干净转化为相应的3-甲基-2-环己烯-1-酮产生影响。当一系列β-溴代烯酮12、14-19与苯基硫代烷基铜盐44-47反应时,通常产生相应的β-烷基烯酮,而且效率高。然而,3-溴代-2-甲基-2-环戊烯-1-酮(19)与铜盐试剂44反应主要产生β-苯基硫代烯酮49。通过使用β-碘代环戊烯酮50代替19,可以避免这种不良结果,后者与44反应顺利,产生高收率的2,3-二甲基-2-环戊烯-1-酮(40)。3-溴代-2-环己烯-1-酮(14)与混合乙烯铜盐试剂48的3当量反应产生3-(3-丁烯基)-2-环己烯-1-酮(32)。1,3-环戊二酮与(Z)-1-氯-2-戊烯烷基化生成化合物51,进一步转化为β-溴代烯酮52。后一物质经二甲基溴化锂处理得到(Z)-茉莉酮(53)。
  • Zn(II)- or Rh(I)-Catalyzed Rearrangement of Silylated [1,1′-Bi(cyclopropan)]-2′-en-1-ols
    作者:Hang Zhang、Changkun Li、Guojun Xie、Bo Wang、Yan Zhang、Jianbo Wang

    日期:2014.7.3
    The rearrangement reactions of silylated alcohols bearing the highly strained structures of cyclopropene and cyclopropanol connected in adjacent positions have been studied under ZnI2- and Rh(I)-catalyzed conditions. The results show intriguing carbon skeletal reorganizations of such system under these conditions. The ZnI2-catalyzed reaction proceeds with C–O cleavage and the rearrangement of the resultant
    在ZnI 2-和Rh(I)催化的条件下,已经研究了在相邻位置连接有环丙烯和环丙醇的高应变结构的甲硅烷基化醇的重排反应。结果表明,在这些条件下,这种系统的碳骨架重组非常有趣。ZnI 2催化的反应随着C–O裂解和所得碳阳离子的重排而进行,从而导致连接两个三元环的C–C单键断裂。相反,Rh(I)催化的反应涉及环丙烯部分的σ键氧化加成,然后环丙烷部分的β-碳消除。
  • Addition reactions of cyclic s-trans-enaminones with Grignard reagents.
    作者:Thomas T. Shawe、Darren B. Hansen、Kelly Ann Peet、Anthony S. Prokopowicz、Patrice M. Robinson、Annatina Cannon、Kathleen E. Dougherty、Andrew A. Ross、Linda M. Landino

    日期:1997.2
    Addition of Grignard reagents to s-trans-enaminones derived from 1,3-cycloalkanediones are described. In dichloromethane, addition of phenylmagnesium bromide gave 3-phenyl substituted cycloalkenones. Alkylmagnesium halides underwent multiple addition reactions, giving mixtures of the 3-alkylcycloalkenones and 1,3-dialkyl-3-(dialkylamino)cyclohexenes. In tetrahydrofuran, only the 3-alkylcycloalkenone

  • New chemistry of cyclic, s-trans-enaminones: Addition of grignard reagents to enaminones derived from 2-methylcyclohexane-1,3-dione
    作者:Thomas T. Shawe、Linda M. Landino、Andrew A. Ross、Anthony S. Prokopowicz、Patrice M. Robinson、Annatina Cannon
    DOI:10.1016/0040-4039(96)00725-3
    日期:1996.5
    Grignard reagents add to cyclic s-trans enaminones to give the cycloalkenone after aqueous hydrolysis. In some cases a competitive double addition takes place. These reactions have been found to be solvent- and reagent-selective.

  • Reaction of cyclic .alpha.-hydroxy epoxides with a strong base: a new 1,2-rearrangement, evidence for a carbenoid pathway.
    作者:Eric Doris、Luc Dechoux、Charles Mioskowski
    DOI:10.1021/ja00156a006
    日期:1995.12
    Several substituted five- and six-membered cyclic alpha,beta-unsaturated ketones are readily available by treatment of the corresponding alpha-hydroxy epoxides with an organolithium reagent. The reaction involves a new carbenoid 1,2-alkyl rearrangement. Evidence for the carbenoid intermediate has been obtained by an intramolecular trapping of the highly reactive species.
