Dehydroabietic acid methyl ester (1) was converted into 7-acetoxydehydroabietic acid methyl ester by direct electrooxidation in acetic acid and 7-oxodehydroabietic acid methyl ester by ruthenium dioxide-mediated oxidation. Non-Kolbe type electrodecarboxylation of 1 resulted in the introduction of a double bond into the ring A of 1.
