  • Synthesis of ketols of the natural pyrethrins
    作者:L. Crombie、P. Hemesley、Gerald Pattenden
    DOI:10.1039/j39690001016
    日期:——
    A stereospecific five-stage synthesis of (±)-cis-pyrethrolone is described, involving cis-octa-1,3-dien-7-one as the key intermediate. The ethylene acetal of this ketone was made by a Wittig reaction, under salt-free condiditions, with vaporised acraldehyde. The overall yield for the synthesis was 21%, and it provides highly pure (pm;)-cis-pyrethrolone for the first time. The material is spectrally
    描述了(±)-顺式-吡咯烷酮的立体有择的五阶段合成,涉及顺式-octa-1,3-dien-7-one作为关键中间体。该酮的乙缩醛是通过Wittig反应在无盐条件下与汽化的丙烯醛反应制得的。合成的总产率为21%,并且它首次提供了高纯度的(pm;)-顺式-吡咯烷酮。该物质与自然(+)-吡咯烷酮样品在光谱上相同。
  • Synthesis of (±)-actinidine by an intramolecular cycloaddition process
    作者:Lyn B. Davies、Sydney G. Greenberg、Peter G. Sammes
    DOI:10.1039/p19810001909
    日期:——
    A new synthesis of (±)-actinidine (1), which relies on intramolecular cycloaddition of an acetylene across a pyrimidine ring, is described. Preparation of 5-(hept-5-yn-2-yl)-4,6-dihydroxypyrimidine (2) followed by thermolysis afforded 1-hydroxyactinidine (13), which could be converted into (±)-actinidine by chlorination and hydrogenation.
    描述了一种新的(±)-act啶(1)合成,该合成依赖于乙炔在嘧啶环上的分子内环加成。制备5-(庚基-5-yn-2-基)-4,6-二羟基嘧啶(2),然后热解,得到1-羟基act啶(13),可以通过氯化和氢化将其转化为(±)-act啶。
  • Implication of a common trimethylenemethane intermediate in dimer formation and structural methylenecyclopropane rearrangement of a bicyclo[3.1.0]hex-1-ene to a 5-alkylidenebicyclo[2.1.0]pentane

  • Annulative ring expansions. Direct conversion of .omega.-alkynyl acetals to polycyclic unsaturated ketones
    作者:Joseph Sisko、Aaron Balog、Dennis P. Curran
    DOI:10.1021/jo00042a007
    日期:1992.7
    Geminal acylation of omega-acetylenic acetals and bis(silyloxy)cycloalkenes under Lewis acid conditions preceded cationic cyclization of the alkyne onto the ketone to produce polycyclic unsaturated ketones.
  • Additive and Medium Effects on Lewis Acid-Promoted Cationic .pi.-Cyclizations of Alkenyl- and Alkynylcyclopentane-1,3-diones
    作者:Aaron Balog、Steven V. Geib、Dennis P. Curran
    DOI:10.1021/jo00107a012
    日期:1995.1
    The effects of nucleophilic additives, Lewis and Bronsted acids, and solvents on BF3.Et(2)O-promoted cationic pi-cyclizations of alkynyl- and alkenylcyclopentane-1,3-diones are reported. The rates and selectivities of alkynyl dione cyclizations were significantly effected by the addition of external nucleophiles or water, and the regioselectivity of cyclization was effected by the choice of reaction solvent. Cyclizations of alkenyl diones, which fail under standard non-nucleophilic conditions, were found to be successful in the presence of added nucleophiles or with Lewis acids other than BF3.Et(2)O. The usefulness of these cationic pi-cyclizations for producing bicyclic ring systems of various functionality was also explored.
