摘　　要：Mesoporous aluminosilica hollow nanospheres were prepared easily,which possess very strong acid site.The heterogeneous catalyst can be utilized in both intramolecular aza-Michael addition cyclization and intermolecular Diels-Alder reaction.The catalyst could be easily recovered and reused.Furthermore,the catalyst could be used in continuous flow chemistry for the uninterrupted synthesis of 2,3-dihydroquinolin-4(1H)-ones,which disclosed the potential application of the present solid catalyst in both academic and industrial syntheses.In addition,the catalyst could be recovered and reused at least 7 times without obvious loss of activity.
