Electroreduction of benzalacetones with an undivided cell in Et4NOTs/acetonitrile gave cyclized dl-hydrodimers as mixtures of two diastereomers. The hydrodimerization proceeded stereoselectively to afford linear dl-hydrodimers, and the following cyclization led to two thermodynamically stable diasteromers of cyclopentanols.
