Abstract
The poly(pyrroles) 1 and 2, synthesized from chiral pyrrole monomers, were used as asymmetric inductors for the electrochemical reduction of prochiral organic molecules. 4-Methylbenzophenone (3) and acetophenone (4) were potentiostatically reduced in DMF+LiBr in the presence of phenol as proton donor, with up to 17% optical purity of the corresponding alcohols. The enantioselectivity depends on the electrolyte used for electropolymerization. Mechanisms of the reduction are presented and discussed.
