An electrochemical synthesis of 4-substituted-cyclopenta[b]pyran derivatives through the one-pot condensation of cyclopentane-1,3-dione, malononitrile, and aldehydes is reported. The reaction is carried out in an undivided cell in the presence of sodium bromide as a supporting electrolyte. Notably, the presented method features high efficiency, excellent yield, and simple experimental procedure.
