A EuIII/EuII photoredox system in alcohol induced an effective hydroxyalkylation at an α-position of a dialkyl malonate.The alcohol adduct was then converted to the lactone.A step-by-step hydroxyalkylation mechanism was suggested in which the Eu ion is used as a photocatalyst and also as a condensation catalyst for the reaction of dialkyl malonates and aldehydes.
