• A Concomitant Allylic Azide Rearrangement/Intramolecular Azide–Alkyne Cycloaddition Sequence
  作者：Rakesh H. Vekariya、Ruzhang Liu、Jeffrey Aubé

  DOI：10.1021/ol500011f

  日期：2014.4.4

  An intramolecular Huisgen cycloaddition of an interconverting set of isomeric allylic azides with alkynes affords substituted triazoles in high yield. The stereoisomeric vinyl-substituted triazoloxazines formed depend on the rate of cycloaddition of the different allylic azide precursors when the reaction is carried out under thermal conditions. In contrast, dimerized macrocyclic products were obtained

  一组互变的烯丙基叠氮化物与炔烃的分子内 Huisgen 环加成反应以高产率提供取代的三唑。当反应在热条件下进行时，形成的立体异构乙烯基取代的三唑恶嗪取决于不同烯丙基叠氮化物前体的环加成速率。相比之下，当使用铜 (I) 催化条件进行反应时，会获得二聚大环产物，这表明通过改变条件来控制反应产物的能力。
• 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

  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）。

  A series of C-2 substituted 3-methylcyclohex-2-enones has been prepared using the Hagemann ester route. A new synthesis of these compounds has been developed which involves the alkylation of the N,N-diethylaminoethyl ether of 1-hydroxy-5-methylcyclohexa-1,5-diene. The cyclohexenones have been converted into the corresponding α,β-epoxyketones using alkaline hydrogen peroxide.

• Synthesis of Angularly Fused Carbocycles via Tandem Radical Cyclization of α-Carbonyl Radicals
  作者：Chandran Prakash、Arasambattu K. Mohanakrishnan

  DOI：10.1002/ejoc.200700986

  日期：2008.3

  An α-carbonyl radical cyclization approach towards the synthesis of angularly fused tricyclic systems is described. On reduction with tributyltin hydride, bromo ketones yield a α-carbonyl radical that undergoes successive 5-exo-dig/trig cyclizations, resulting in two or four contiguous stereocenters.

  δ-unsaturated amide, prepared by an amide acetal Claisen rearrangement, has been subjected to hydroxy-lactonisation, and reductive cleavage of the corresponding keto-lactone with aluminium amalgam has led to a trisubstituted cyclohexanone derivative with retention of configuration, thus establishing a new method for the stereocontrolled synthesis of 2,3,3-trisubstituted cyclohexanones.

  通过酰胺缩醛Claisen重排制备的γ，δ-不饱和酰胺已经进行了羟基内酯化，相应的酮内酯与铝汞齐的还原裂解导致三取代的环己酮衍生物具有构型保留，从而建立了立体控制合成2,3,3-三取代的环己酮的新方法。
