Acrylamide and aromatic aldehydes were found to undergo the Baylis-Hillman reaction at ambient temperature and pressure in an aqueous medium in the presence of a stoichiometric amount of DABCO, to give the corresponding 3-hydroxy-2-methylenepropionamides in excellent yield. A faster, but reversible side reaction gave N-acylhemiaminals, which later disappeared, as the desired Baylis-Hillman adducts were formed as major products over an extended period of time.
