Procedure

Ethyl crotonate (6.7% by weight) and 2-methylpentanal (5.9% by weight) were reacted electrochemically by a method analogous to example 3 (all % by weight are based on the total aqueous reaction electrolyte). A yield of 4-(2-pentyl)butyrolactone of 66.7% and a yield of the corresponding ethyl γ-hydroxycarboxylate of 26.6% were achieved. This corresponded to a total yield of target products of 93.2% of the theoretical yield.
