  • Manganese(III)-Based Facile Synthesis of 3-Cyano-4,5-dihydrofurans and 4-Cyano-1,2-dioxan-3-ols Using Alkenes and Acylacetonitrile Building Blocks
    作者:Van-Ha Nguyen、Hiroshi Nishino、Kazu Kurosawa
    DOI:10.1055/s-1997-1282
    日期:1997.8
    New 3-cyano-4,5-dihydrofurans and 4-cyano-1,2-dioxan-3-ols were alternatively synthesized in good yields by the oxidation of acylacetonitrile building blocks with manganese(III) acetate in the presence of alkenes without any byproducts. The reaction at reflux temperature gave 3-cyano-4,5-dihydrofurans under an argon atmosphere, while 4-cyano-1,2-dioxan-3-ols were obtained at 23°C under an air atmosphere except for the reaction of styrene with benzoylacetonitrile which afforded 2-cyano-1,4-diphenylbutane-1,4-dione, and the reaction of 1,1,-diphenylethene with 2-(2-cyano-1-oxoethyl)-5-methylfuran which yielded 2-cyano-4,4-diphenylbutanolide without any cyclic peroxides. The oxidation of benzoylacetonitrile itself at 23°C under an air atmosphere in the absence of alkene gave benzoic acid. Easy conversion of the 1,2-dioxanes to furans was demonstrated, and mechanisms for the formation of dihydrofurans and dioxans as well as the unusual transformation to butanedione and butanolide were also discussed.
    新型3-氰基-4,5-二氢呋喃和4-氰基-1,2-二氧杂环-3-醇通过在烯烃存在下,用醋酸锰(III)对酰基乙腈构建块进行氧化,获得了良好产率且没有副产物。回流温度下的反应在氩气气氛中生成3-氰基-4,5-二氢呋喃,而在空气气氛下23°C下反应则获得4-氰基-1,2-二氧杂环-3-醇,除了苯甲基乙腈与苯乙烯的反应生成了2-氰基-1,4-二苯基丁-1,4-二酮,以及1,1-二苯乙烯与2-(2-氰基-1-氧代乙基)-5-甲基呋喃的反应生成2-氰基-4,4-二苯基丁内酯,没有生成任何环状过氧化物。苯甲基乙腈本身在空气气氛下23°C的氧化反应在缺乏烯烃的情况下产生了苯甲酸。还展示了1,2-二氧杂环转化为呋喃的简便过程,同时讨论了二氢呋喃和二氧杂环的形成机制,以及向丁二酮和丁内酯的不寻常转化。
  • Olefin-Insertion Reaction between the Carbonyls of Benzils; Formation of 1,4-Diketones by Michael Additon Catalyzed by Cyanide Ion
    作者:Akira Miyashita、Atsushi Numata、Yumiko Suzuki、Ken-ichi Iwamoto、Takeo Higashino
    DOI:10.1246/cl.1997.697
    日期:1997.8
    Benzils (1) react with Michael addition acceptors (2) in the presence of cyanide ion as a catalyst to give 1,4-diketones (3), which are products of ethylene group insertion between the carbonyls of the benzils. The 1,4-diketones (3) are produced through the formation of the O-aroylmandelonitrile anion, followed by Michael addition and rearrangement of the aroyl group with decyanation.

    作者:Tarek S. Mansour
    DOI:10.1016/0040-4039(88)85183-9
    日期:1988.1
    In the presence of Hunig's base and anhydrous magnesium chloride benzoylacetonitrile (1) reacts with 2-haloketones and -esters to give C-alkylated products which may cyclize to polysubstituted furans whereas with acid chlorides O-acylated products are obtained as separable mixtures of e and Z isomers.

    作者:Akira MIYASHITA、Yoshiyuki MATSUOKA、Atsushi NUMATA、Takeo HIGASHINO
    DOI:10.1248/cpb.44.448
    日期:——
    The anions derived form O-aroylmendelonitriles 1 reacted with Michael addition acceptors such as acrylonitrile (7) and methyl acrylate (10) to give the corresponding 1, 4-diketones 12, 13, and 15 in moderate to good yields. Under acidic conditions, the 1, 4-diketones 12, 13, and 15 were converted into the furans 17, 18 and 19 in good yields.
    O-aroylmendelonitriles 1 衍生出的阴离子与迈克尔加成受体(如丙烯腈 (7) 和丙烯酸甲酯 (10))反应,得到相应的 1,4-二酮 12、13 和 15,收率中等至良好。在酸性条件下,1, 4-二酮 12、13 和 15 可以很好地转化为呋喃 17、18 和 19。
