Electroreduction of y-and 6-cyanoketones in i-PrOH gave cyclized products a-hydroxyketones and their dehydroxylated ketones, and this reaction was applied to the synthesis of dihydrojaswone, methyl dihydrojaswonate, and Rosaprostol. We have previously reported sowe unique electroreductive intramolec
