A novel synthetic protocol has been developed for the synthesis of 1,4-benzoxazinone-acetylphenylallyl quinazolin-4(3H)-one hybrids 7a–n by employing Pd-catalyzed CH arylation in presence of 5–10% phosphine ligand in good to excellent yields and evaluated for their anti-proliferative activity against three cancer cell lines such as A549 (lung), HeLa (cervical), MDA-MB-231 (breast).

A new series of novel quinazolinones with allylphenyl quinoxaline hybrids 9a-n were efficiently synthesized in good yields by the reaction of 3-allyl-2-methylquinazolin-4(3H)-one (5a-n) with bromophenyl)quinoxaline (8) utilizing Pd catalyzed Heck-cross coupling and evaluated for anti-proliferative activity against four cancer cell lines such as HeLa (cervical), MIAPACA (pancreatic), MDA-MB-231 (breast)

An efficient and straightforward strategy to synthesize a wide range of quinazolinone derivatives from commercially inexpensive 2-aminobenzamides and various amino acids via molecular iodine promoted oxidative decarboxylation of α-amino acids, followed by oxidative cyclization reaction, is revealed. Operational simplicity, consistent yield, functional group tolerance and sustainability are the other
