Summary, etc. |
<p style="text-align: justify;">This research presents the synthesis of new quinazolinone-based Mannich bases in good yields <em>via</em> a three-step procedure. The first step is the reaction of 6-hydroxyanthranilic acid <strong>1</strong> with an excess of acetic anhydride at 150°C for 2 h to afford benzoxazinone <strong>2</strong> in 87% yield. Compound <strong>2</strong> is then reacted with 4-aminophenol in DMSO at reflux for 7 h to give compound <strong>3 </strong>in 75% yield. Finally, the reaction of <strong>3</strong> with paraformadehyde and secondary amines in ethanol affords new quinazolinone-based Mannich bases <strong>4a-c</strong> and <strong>5a-e</strong> in 55-70% yields. The structure of Mannich bases have been characterized by NMR and MS spectra. The bio-assay results show that some new Mannich bases exhibited weak to moderate cytotoxic activity against SKLu-1 and MCF-7 cell lines.</p> |
