Abstract
A series of 6-substituted quinazolinone derivatives were prepared by the reaction of 6-bromoquinazolinones with aryl or alkyl amines and thiols, in the presence of a Pd(OAc)2/Xantphos system, under Buchwald–Hartwig-type reaction conditions. The 6-bromoquinazolinones were obtained in the three-components reaction of 5-bromoisatoic anhydride, triethyl orthoformate and an appropriate amine. Biological screening of the potential cytotoxicity of synthesized compounds on HT29 and HCT116 cell lines, as well as on the lymphocytes, showed that some derivatives of quinazolinone have significant anticancer activities. The detailed synthesis, spectroscopic data, and biological assays were reported.Graphical abstract
