  • Oxidative scission of ethyl 2,2-dimethoxycyclopropanecarboxylates with lead tetraacetate. Synthesis of the unusual anhydride bis-acetals
    作者:M.Liliana Graziano、Vincenzo Piccialli

    日期:1999.11
    The reaction of ethyl 2,2-dimethoxycyclopropanecarboxylates 1–3 with lead tetraacetate (Pb(OAc)4, LTA) in benzene leads to the oxidative scission of the C1C2 bond. Monoalkylated fumric acid diesters 4 and 5 are obtained from 3-alkylcyclopropanes 1 and 2, respectively, along with dimeric species for which we propose the unusual anhydride bis-acetal structure 6 or 7, respectively. Reaction of 3,3-dimethylcyclopropane

  • Bromination and iodination of donor–acceptor cyclopropanes. Evidence for an ET mechanism

    presence of pyridine, NBS, trimethyl phosphate, and iodination with ICl and ICl/pyridine has been also performed. A common SET mechanism may be proposed for both halogenations; depending on the reaction conditions, bromination can also occur via acid-catalysed or SE2 routes. The reaction of the 2-ethoxyanalogues cis-12 and trans-12 with the same halogens proceeds in a similar manner, giving 3-formyl-2-haloesters

Methyl ethyl oxobutanedioates 2a-d were obtained in the first case while the 3-substituted ethyl methyl 2-oxopentanedioates 6a and 6b in the second one.

    1a. The presence of TiCl4 influences the stereochemistry of the reaction with chloride 3 while it is essential for reaction of the less reactive PhSeCN 4. With this electrophile the reactions lead to α,α-dimethoxycarbonitriles 13a–d while only 1a and 1b give also the expected cyanoselenenyl derivatives 12a and 12b. Moreover, from 1b compound syn- 5b is obtained, and 1a gives, via the alkene 2a, esters
