摘要:
The inclusion complex of isatoic anhydride with beta-cyclodextrin was formed as a result of intermolecular interaction between isatoic anhydride with beta-CD. The inclusion complex was confirmed by IR spectroscopy, X-ray diffraction and DSC studies. From application of complex, herein we have described a simple and efficient protocol for synthesis of 2, 3-dihydroquinazoline-4(1H)-one derivatives by one pot condensation of isatoic anhydride, ammonium acetate or amine and aldehyde using beta-CD as a supramolecular catalyst in aqueous media.
