  • Asymmetric induction in the cycloaddition reaction of dichloroketene with chiral enol ethers. A versatile approach to optically active cyclopentenone derivatives.
    作者:Andrew E. Greene、Florence Charbonnier
    DOI:10.1016/s0040-4039(01)80878-9
    日期:1985.1
    Significant asymmetric induction has been observed in the cycloaddition reaction of dichloroketene with chiral enol ethers. The resultant diastereomeric cyclobutanones have been converted to synthetically useful α-chlorocyclopentenones in optically active form.
    在二氯乙烯与手性烯醇醚的环加成反应中观察到明显的不对称诱导。所得非对映体环丁酮已被转化为旋光形式的合成上有用的α-氯环戊烯酮。
  • Enantioselective Formation of Bicyclic Lactones by Rhodium-Catalyzed Intramolecular CH-insertion reactions
    作者:Paul Müller、Philippe Polleux

    日期:1994.5.11
    leads to a 3:1 cis/trans mixture of bicyclic lactone 6a with an enantiomeric excess of 95–97% (cis) and 90% (trans). The conformationally rigid tert-butyl derivatives 5b and 5c afford, in the presence of the same catalyst, 6b and 6c, respectively, via insertion into the equatorial CH bonds exclusively, with ee's of ca. 95%. A remarkable degree of induction (92–95%) results in the lactone 6g upon decomposition
    在手性[Rh 2 ((2 S)-mepy} 4 ]]存在的情况下,重氮基乙酸环己酯(5a)的分解导致双环内酯6a的3:1顺式/反式混合物,对映体过量为95-97 %(顺式)和90%(反式)。在相同催化剂的存在下,构象刚性的叔丁基衍生物5b和5c分别仅通过插入到赤道CH键中而得到ee,其ee分别为6b和6c 。95%。1-偶氮-2-甲基丙基重氮基乙酸酯(5g)分解后,内酯达到6g时,诱导度显着(92-95%)。由1-甲基环己醇,环戊醇和1-甲基环戊醇(5d–f)衍生的重氮乙酸酯在相似条件下提供的插入产物具有较高的非对映选择性,但对映选择性明显较低。其他催化剂效率较低。
  • α,β-Unsaturated and cyclopropyl acyl radicals, and their ketene alkyl radical equivalents. Ring synthesis and tandem cyclisation reactions

    25a on treatment with Bu(3)SnH-AIBN. Furthermore, in the presence of methanol the only product from this reaction was the bis(methyl ester) dimer 25b, thereby lending further credence to the involvement of ketene alkyl radical intermediates in these reactions, and in the aforementioned reactions involving 2,6- and 2,7-diene selenyl esters. Treatment of the cyclopropane selenyl esters and , containing
    用Bu(3)SnH-AIBN处理α,β-不饱和硒基酯12和14分别通过推测的α-烯酮烷基自由基中间体产生相应的2-环己酮13和15。10.相反,2,7-二烯酯34和39经历串联自由基环化,产生二喹烷,例如(76%),并且相应的丙二烯取代的α,β-不饱和硒烯基酯48在用Bu处理时得到环辛二烯酮56。 (3)SnH-AIBN在回流的苯中。衍生自菊花酸的硒基酯19经Bu(3)SnH-AIBN处理后,会生成γ-δ-不饱和醛22和相应的二聚体25a的混合物。此外,在甲醇存在下,该反应的唯一产物是双(甲酯)二聚物25b,因此进一步证明了烯酮烷基自由基中间体在这些反应中以及在涉及2,6-和2,7-二烯硒烯基酯的上述反应中的参与。用Bu(3)SnH-AIBN处理环丙烷硒烯基酯和在其侧链中含有酮和氧基官能团的化合物,可以很好地合成烯醇内酯66(76%)和反式稠合双环[ 6.1.0]壬烷67(80-95%)。

  • Nitroalkenes as electrophiles in the asymmetric Michael reaction involving chiral imines/enamino esters
    作者:Cyrille Thominiaux、Sébastien Roussé、Didier Desmaële、Jean d'Angelo、Claude Riche
    DOI:10.1016/s0957-4166(99)00180-9
    日期:1999.5
    Addition of 2-nitropropene to the chiral imine derived from 2-methylcyclopentanone and (S)-1-phenylethylamine furnished the expected Michael adduct. The latter compound was then efficiently converted into (R)-pentalenone through a Nef reaction. Condensation of the enamino ester derived from 2-carbethoxycyclopentanone and (S)-1-phenylethylamine with 1-nitropropene gave with excellent diastereo- and enantioselectivity the corresponding Michael adduct.
