Abstract: The Baylis-Hillman adducts, 3-aryl-3-hydroxy-2-methylene-alkanoates and 3-aryl-3-hydroxy-2-methylene-alkane­nitriles have been efficiently isomerized to the corresponding (<i>E</i>)-cinnamyl alcohols by treatment of the adducts with Ac<sub>2</sub>O in the presence of Amberlyst-15 followed by hydrolysis of the intermediate acetates with K<sub>2</sub>CO<sub>3</sub>/MeOH. The first step occurs under solvent-free conditions and the catalyst has been found to be reusable.
