  • A Radical Bidirectional Fragment Coupling Route to Unsymmetrical Ketones
    作者:Lucile Anthore-Dalion、Qiang Liu、Samir Z. Zard
    DOI:10.1021/jacs.6b05344
    日期:2016.7.13
    A powerful strategy for the regioselective bidirectional synthesis of unsymmetrically substituted ketones is described, relying on the fact that the exchange of a xanthate is much faster than the radical addition to an unactivated alkene. The use of an alkene as the formal "alkylating" agent associated with the tolerance for numerous functional groups and the mildness of the experimental conditions
    描述了不对称取代酮的区域选择性双向合成的强大策略,依赖于黄药的交换比未活化烯烃的自由基加成快得多的事实。使用烯烃作为正式的“烷基化”剂,与许多官能团的耐受性和实验条件的温和性相关,消除了与经典离子和过渡金属方法相关的许多问题。
  • Formation of α-iminoketones and α-diimines versus Favorskii rearrangement products from the reaction of α,α′-dibromoketones and primary amines
    作者:Norbert De Kimpe、Luc D'Hondt、Luc Mones
    DOI:10.1016/s0040-4020(01)92258-6
    日期:1992.4
    reaction of aliphatic acyclic α,α′-dibromoketones with primary amines gave rise to α-iminoketones and α-diimines. Both reaction products could be selectively obtained under appropriate reaction conditions. Sterically hindered α,α-dibromoketones did not react with primary amines, although, under forcing conditions the Favorskii rearrangement could be induced. In aqueous methanol, α,α′-dibromoketones reacted
    脂族无环α,α′-二溴酮与伯胺的反应产生α-亚氨基酮和α-二亚胺。两种反应产物都可以在适当的反应条件下选择性地获得。受位阻的α,α-二溴酮不与伯胺反应,尽管在强迫条件下可以诱导Favorskii重排。在甲醇水溶液中,α,α'-二溴代酮与伯胺反应生成Favorskii重排,而不是α-亚氨基酮的形成。脂环族α,α'-二溴代酮对伯胺的行为不同,因为五元环提供2-(N-烷基)氨基-2-环戊烯酮,而六元环引起Favosskii环收缩。
  • Inhibitors of Thermus thermophilus Isopropylmalate Dehydrogenase
    作者:Michael C. Pirrung、Hyunsoo Han、Richard T. Ludwig
    DOI:10.1021/jo00088a026
    日期:1994.5
    In an attempt to use mechanism-based design for the discovery of inhibitors of the isopropylmalate dehydrogenase from T. thermophilus, we have prepared and studied a number of potential mimics for an intermediate in the oxidative decarboxylation of isopropyl malate, the enol or enolate of alpha-ketoisocaproate. Because hydroxamate and dicarboxylate enolate mimics are strong, uncompetitive inhibitors of the enzyme and vinyl fluoride enol mimics are weak, competitive inhibitors, it is suggested that the reaction involves the enolate. The uncompetitive inhibition by a number of anionic compounds suggests, in combination with previous studies in other laboratories, that they mimic the enolate product of the decarboxylation. An explanation for the potency of the inhibition of IMDH by these compounds is proposed based on the electrostatic interaction of product and cofactor.

  • Remote control of stereogenicity transfer by ring-generated anisotropic orbital overlap. Stereochemistry of hydrogen shift in the intramolecular reverse ene reaction of a cis-2-alkyl-1-alkenylcyclopropane
    作者:Patti A. Parziale、Jerome A. Berson
    DOI:10.1021/ja00012a032
    日期:1991.6
    Pyrolysis of 5 gave only 2-methyl-octa-2(Z),5(Z)-diene-1-d 3 -7(S)-d, with high stereospecificity at each of the three sites of sterogenicity. This result is the one predicted if the reaction is controlled by optimal overlap of the reacting C―H and π bond orbitals with the C s symmetric component of the degenerate 3E' highest occupied orbital of the cyclopropane ring
