-050Reduction of N-2-Substituted Benzimidazoyl Imidates. -Cathodic reduction of iminoesters is studied by cyclic voltammetry and controlled potential electrolysis at mercury electrode in aprotic DMF. Iminoesters bearing an N-alkoxycarbonyl group such as (I) undergo reductive cyclization to give oxadiazine derivatives (II), whereas iminoesters (III) having an N-acyl group undergo ordinary reduction of the carbonyl function. -(ABDERRAHIM, R.; MEDINI, H.; KOSSAI, R.; BOUJLEL, K.; Synth.
