Reduction of N‐2‐Substituted Benzimidazoyl Imidates.

ABSTRACT> Cathodic reduction of several iminoesters ( 1 ) and ( 2 ) has been investigated by cyclic voltammetry and controlled potential electrolysis at mercury electrode in aprotic DMF, leading to the formation of two reduction steps. The appropriate choice of the nature of R2 groups allowed the reductive cyclisation when R2 is an ethoxy (or alkoxy) group.
