  • Reactions of Phenyltriazolinedione with Alkenes. Stereochemistry of Methanol Adducts to Aziridinium Imide Intermediates
    作者:Ioulia Smonou、Saeed Khan、Christopher S. Foote、Yiannis Elemes、Irene M. Mavridis、Ariadne Pantidou、Michael Orfanopoulos

    The addition of 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) and the stereochemistry of methanol/PTAD adduct formation with cis- and trans-2-butenes, 1-methylcyclopentene, (E)-2-methyl-2-butene-1,1,1-d(3), and substituted indenes (indene, 2-methylindene, 2,3-dimethylindene) have been investigated. There is no loss of stereochemistry in the addition of MeOH and PTAD to butenes, 1-methylcyclopentene, 2-methyl-2-butene, and indene. However, in methyl-substituted indenes 9 and 14, loss of stereochemistry at the reaction center is observed. An aziridinium imide (AI) is proposed as an intermediate in all these systems. The stability of the AI intermediate and its equilibration with an open zwitterion depend on the particular system. Only in the benzylically-stabilized tertiary indenes is the open zwitterion stable enough to cause loss of stereochemistry.
  • Photochemical Reactions in the Interior of a Zeolite. Part 5: The Origin of the Zeolite Induced Regioselectivity in the Singlet Oxygen Ene Reaction
    作者:Edward L Clennan、Jakub P Sram
    DOI:10.1016/s0040-4020(00)00514-7
    日期:2000.9
    Photooxidations of several new alkenes in the interior of methylene blue doped NaY are reported. The results suggest that the novel regiochemistry of these reactions can be rationalized by invoking both cation complexation with the alkenes and electrostatic interaction between the cation and the pendant oxygen on the developing perepoxide.

  • Control of Regioselectivity by the <i>l</i><i>one</i> Substituent through Steric and Electronic Effects in the Nitrosoarene Ene Reaction of Deuterium-Labeled Trisubstituted Alkenes
    作者:Waldemar Adam、Oliver Krebs、Michael Orfanopoulos、Manolis Stratakis

    日期:2002.11.1
    For the ene reaction of 4-nitronitrosobenzene (ArNO) with a variety of primary and secondary lone alkyl-substituted substrates, the twix/twin regioselectivity is constant at about 85:15. In contrast, for the lone tert-butyl group and for lone aryl substituents, the twix regioisomer is obtained exclusively. These regioselectivities have been rationalized in terms of steric interactions and coordination
