  The reactions of ketone dilithio α,β-dianions with imines and hydrazones were investigated. The nucleophilic addition reaction to C–N double bonds took place selectively at the β-position of dianions to form lithium Z-enolates containing a lithium amide portion, which is then transformed into γ-amino ketones and related compounds by the subsequent reaction with electrophiles.

  The cross-coupling reaction of dianion cuprates, generated from ketone α,β-dianions and copper salts, with acid chlorides, was studied. The reaction gave good to moderate yields of unsymmetrical 1,4-diketones. The consecutive treatment of a dianion cuprate with cyclohexanecarbonyl chloride and methyl iodide or two different acid chlorides gave 2-methyl-substituted 1,4-diketone or triketone, respectively

  研究了由酮α，β-二价阴离子和铜盐生成的二价铜酸盐与酰氯的交叉偶联反应。该反应给出了不对称的1，4-二酮的良好至中等产率。用环己烷羰基氯和碘甲烷或两种不同的酰氯连续处理二价铜酸盐，分别得到2-甲基取代的1，4-二酮或三酮。

  [reaction: see text] Ketone alpha,delta-dianions are generated by vinylogous extension of ketone alpha,beta-dianions with alkenes such as vinylarenes, vinylsilanes, and vinyl sulfides, which then undergo reactions at the delta and alpha positions with different electrophiles, creating ketone frameworks. This work represents a cascade-type anion method that achieved three- and four-carbon component

  [反应：请参阅文字]酮α，δ-二价阴离子是通过将酮α，β-二价阴离子与烯键（如乙烯基芳烃，乙烯基硅烷和乙烯基硫化物）乙烯基延伸而产生的，然后这些烯在δ和α位与不同的亲电试剂发生反应，创建酮框架。这项工作代表了一种级联型阴离子方法，该方法实现了三碳和四碳组分的组装反应，从而产生了酮。

  Ketone dilithio alpha,beta- and alpha,beta'-dianions can be generated by a tin-lithium exchange reaction of the lithium enolate of beta-tributyltin substituted ketones. A chelation-aided approach, which employs beta-dichlorobutyltin substituted ketones and n-BuLi, is also useful for the generation of ketone alpha,beta-dianions having the Z-geometry at the alkene. The generated dianions can be transformed into substituted ketones by reaction with various carbon electrophiles. (c) 2005 Elsevier Ltd. All rights reserved.
