Substituted-6-methyl-1-thioxo-1,2-dihydro-3H-furo[3,2-g]pyrimido[1,6-a]quinazolin-3-ones (5a,b) were synthesized from condensation of visnagenone (2a) or khellinone (2b) with 6-amino-thiouracil (3) in dimethylformamide or refluxing of (4a) or (4b) in dimethylformamide. Hence, compounds (5a,b) were used as the starting materials for preparing many new heterocyclic compounds such as; furo[3,2-g]pyrimido[1,6-a]quinazoline (6a,b), furo[3,2-g]thiazolo[2′,3′:2,3]pyrimido[1,6-a]quinazolinone (7a,b), substituted-benzylidene-furo[3,2-g]thiazolo[2′,3′:2,3]pyrimido[1,6-a]quinazoline-3,5-dione (8a–f), 3-o

Background Tinibs were a kind of important epidermal growth factor receptor (EGFR) inhibitors used as potential therapeutic agents in treating non-small cell lung cancer (NSCLC) in clinic. The drug resistance of clinical used tinibs made the development of more active tinib analogues an attractive field in research. Quinazoline ring was regarded as the key fragment in tinibs and quinazolinone was indispensible intermediate in the synthesis of quinazoline. Thus, synthesis of quinazolinone intermediates was a key step which would further limit the overall yield of final product of tinib analogue

Abstract:
Investigations into radical and palladium(0) cyclisations onto the C-2 position of the 3H-quinazolin-4-one moiety have been made. This has led to the syntheses of a number of biologically active quinazolinone natural products using alkyl, heteroaryl and acyl radical cyclisations. The reactions proceeded via a homolytic aromatic substitution mechanism. As such, fully rearomatised products were recovered. A C-2 radical 3H-quinazolin-4-one building block was also prepared. This turned out to have only limited synthetic applications. Radical cyclisations onto aryl groups were carried out using thi
