摘　　要：An efficient and direct procedure has been developed for the preparation of amidoalkyl naphthols by a one-pot condensation of aryl aldehydes,2-naphthol and urea or amides,in the presence of HClO_4-SiO_2 as a heterogeneous catalyst.The reactions were carried out under reflux and solvent-free conditions.The present methodology offers several advantages such as excellent yields, simple procedure,easy work-up and ecofriendly reaction condition.The catalyst is easily prepared,stable,reusable and efficient under the reaction conditions. 关键词：HClO4-SiO2 二氧化硅多相催化反应多元反应
