摘要
Direct aldol reactions of aldehydes and ketones can proceed smoothly in the presence of a catalytic amount of naphthol/sodium naphtholate（5 mol%） to afford the corresponding products with yields up to 98%.Such a bifunctional catalyst is more moderate than strong acid or base employed in direct aldol reactions.
