摘要

Substituted 2-aryl-2, 3-dihydroquinazolin-4 (1H)-ones were prepared for the first time in water under neutral conditions by the reaction of aniline, isatoic anhydride, and aldehyde mediated by β-cyclodextrin in good yields. β-Cyclodextrin can be recovered and reused with a little loss of catalytic activity.
