Electrocatalytic transformation of malononitrile and cycloalkylidenemalononitriles into spirotricyclic and spirotetracyclic compounds containing cyclopropane and pyrroline fragments
摘要:
Electrolysis of cycloalkylidenemalononitriles and malononitrile in MeOH in all undivided cell in the presence of the NaBr-NaOMe mediator system gives spirotricyclic compounds containing cyclopropane and pyrroline fragments in 50-77% yields. Spirobicyclic and spirotricyclic tetracyanocyclopropanes undergo electrolysis ill alcohols to afford spirotricyclic and spirotetracyclic products containing cyclopropane and pyrroline fragments ill 50-93% yields.
