An efficient one-pot, three-component synthesis of quinazolinone derivativescontaining 3-acrylamino motif was carried out using CeO2 nanoparticles as catalyst. Thirty-nine synthesized compounds were obtained with satisfied yield and elucidated by spectroscopic analysis. Four phytopathogenic fungi were chosen to test the antifungalactivities by minimum inhibitory concentration (MIC) method. Compounds
Abstract In this research, a facile, effective and one-pot synthesis of new quinazoline-4(1 H )-one derivatives is reported. Isatoic anhydride, acid hydrazides or ammonium acetate and aromatic aldehydes in the presence of N -halosulfonamides; N , N , N ′, N ′-tetrabromobenzene-1,3-disulfonamide and poly( N -bromo- N -ethylbenzene-1,3-disulfonamide) are used to produce the above-mentioned compounds
