| Abstract: | Summary. 2,3-Dihydroquinazolin-4(1H)-ones were efficiently synthesised by the reaction of isatoic anhydride, a primary amine or ammonium acetate, and different
aromatic aldehydes in 1-butyl-3-methylimidazolium tetrafluoroborate (bmim]BF4) without using any acidic catalyst. Also a bis-derivative of the title compound as a polyheterocyclic system was synthesised
successfully in high yield. |
