Stereoselective electrocatalytic transformation of malonate and alkylidenecyanoacetates into (E)-3-substituted 2-cyanocyclopropane-1,1,2-tricarboxylates

Electrolysis of malonate and alkylidenecyanoacetates in alcohols in an undivided cell in the presence of NaBr results in stereoselective formation of (E)-3-substituted 2-cyanocyclopropane-1,1,2-tricarboxylates in 75-90% yields. (c) 2006 Published by Elsevier Ltd.
