    An efficient palladium catalyzed diastereoselective addition of arylboronic acids to complex spirocyclopropyl dinitriles is developed in the presence of a catalytic amount of 4-dodecylbenzenesulphonic acid (DBSA) as a Brønsted acid surfactant in aqueous media. The protocol is also found to be highly effective when different types of nitrile compounds and organo-boron compounds are used. The overall

    Pyridinium bromide has been tested as a new mediator for electrochemical transformations in methanol and acetonitrile. An efficient protocol for the synthesis of cyclopropanes via the electrochemical transformations of alkylidenemalononitriles and C-H acids (malononitrile, malonic ester, N,N-dimethylbarbituric acid, pyrazolin-5-ones) has been developed. The chemistry proceeds in a simple undivided

  • Electrocatalytic and chemical methods in MHIRC reactions: the first example of the multicomponent assembly of medicinally relevant spirocyclopropylbarbiturates from three different molecules
    作者:Anatolii N. Vereshchagin、Michail N. Elinson、Evgeniya O. Dorofeeva、Nikita O. Stepanov、Tatiana A. Zaimovskaya、Gennady I. Nikishin
    DOI:10.1016/j.tet.2012.12.029
    日期:2013.2
    Electrolysis of aldehydes, barbituric acids, and malononitrile in alcohol in an undivided cell in the presence of sodium bromide results in efficient MHIRC formation of the corresponding spirocyclopropylbarbiturates in 50-65% substance yield. The electrocatalytic reaction smoothly proceeds under neutral and mild conditions with aromatic aldehydes bearing both electron-donating and electron-withdrawing groups. The implication of electrocatalysis in MHIRC reaction is an efficient approach to medicinally relevant spirocyclopropylbarbiturates avoiding the inconvenient direct use of molecular halogen or halogenated substrates.
