    使用多相 Pt-Ni 合金催化剂进行四取代烯烃的非对映选择性加氢
    摘要:
    开发了一种 Pt-Ni 合金纳米催化剂,用于环戊烯支架中四取代烯烃的非对映选择性定向氢化。对于此类底物,已建立的均相催化剂会产生氢解副产物,而商业多相催化剂不具有立体选择性。贵金属和贱金属的均匀合金化与高催化剂分散相结合对于一系列空间位阻烯烃的良好反应性和非对映选择性至关重要。

    Reaction of cyclic .alpha.-hydroxy epoxides with a strong base: a new 1,2-rearrangement, evidence for a carbenoid pathway.
    摘要:
    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.

    developed to easily transform a cyclopentenone derivative into trans‐Magnolione® and dehydro‐Magnolione®. The rearrangement of exocyclic allylic alcohols was tested as well, and a dynamic kinetic resolution was observed: α,β‐unsaturated ketones with (E)‐configuration and a high diastereomeric excess were synthesized. Finally, the 2,2,6,6‐tetramethyl‐1‐piperidinium tetrafluoroborate (TEMPO+BF4−)/laccase

    analysis of the chemistry of vinylogous acyl triflates provides insight into important chemical processes and opens new directions in synthetic technology. Tandem nucleophilic addition/C-C bond cleaving fragmentation reactions of cyclic vinylogous acyl triflates 1 yield a variety of acyclic acetylenic compounds. Full details are disclosed herein.

  • 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

    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)。

    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

    A variety of α,β-unsaturated ketones are conveniently synthesized from enaminoketones and organolithium compounds especially when the reaction is carried out in petroleum ether; this reaction provides a facile method for the synthesis of α,β,γ-trisubstituted 2-cyclopentenones in combination with the regioselective alkylation of enaminoketones.
