    .alpha.,.beta.-Unsaturated Acetals as Precursors of .alpha.-Substituted Ethoxy Dienes. Useful Reagents for Nucleophilic Acylation
    摘要:
    The reaction of (E)-1,1-diethoxybut-2-ene (1a) and 1,1-diethoxy-3-methylbut-2-ene (1b) with 2 equiv of sec-butyllithium complexed with potassium tert-butoxide (Schlosser's base) in THF at -95 degrees C gives 1-metalated 1-ethoxy 1,3-dienes that are synthetically equivalent to acyl anions. Subsequent reaction with suitable electrophiles, such as alkyl halides, aldehydes, ketones, carbon dioxide, and carboxylic acid derivatives, affords (E)-1-substituted 1-ethoxy 1,3-dienes 2a-i. Experimental procedures are given for the reaction of the carbanionic intermediates with the electrophiles. Some typical examples for the conversion of the produced alpha-substituted alkoxy dienes into the corresponding alpha,beta-unsaturated carbonyl compounds are also reported. In particular, in the case in which crotonaldehyde is used as an electrophile, the addition product 2c undergoes acid-catalyzed conversion to compounds 4c, 5c, and 6c as a function of the experimental conditions.

  • LIC-KOR promoted formation of conjugated dienes as useful building blocks for palladium-catalyzed syntheses
    作者:Annamaria Deagostino、Manuele Migliardi、Ernesto G. Occhiato、Cristina Prandi、Chiara Zavattaro、Paolo Venturello

    It is demonstrated that α,β-unsaturated acetals can be considered a synthetic tool for transforming carbonyl derivatives into cheap and easily accessible starting materials for the construction of various and more complex structures. The lithium–potassium mixed superbase LIC-KOR induces a conjugate elimination reaction that converts α,β-unsaturated acetals into 1E-1-alkoxybuta-1,3-dienes. These derivatives
    已经证明,α,β-不饱和缩醛可以被认为是用于将羰基衍生物转化成廉价且易于获得的起始材料以用于构建各种和更复杂的结构的合成工具。锂-钾混合超碱LIC-KOR引起共轭消除反应,该反应将α,β-不饱和缩醛转化为1 E -1-烷氧基丁1,3-二烯。这些衍生物可以很容易地就地金属化并通过与亲电试剂反应而官能化。结果可分为两部分:(1)烷氧基二烯基硼酸酯与四氢萘醌或异苯并二氢吡喃酮衍生的乙烯基三氟甲磺酸酯之间的钯催化交叉偶联反应;(2)在钯催化剂的存在下与芳基衍生物的区域和立体选择性交叉偶联反应(Heck条件)。
