Synthesis and bioactivity evaluation of novel arylimines containing a 3-aminoethyl-2-[(p-trifluoromethoxy)anilino]-4(3H)-quinazolinone moiety

Twenty-seven novel (E)-3-[2-arylideneaminoethyl]-2-[4-(trifluoromethoxy) anilino]-4(3H)-quinazolinone derivatives were synthesized by reacting various aromatic aldehydes with intermediate 6. The target compounds were characterized by 1H NMR, s

Design, synthesis, and evaluation of new 4(3H)-quinazolinone derivatives containing a pyrazole carboxamide moiety

A total of 15 new 4(3H)-quinazolinone derivatives containing a pyrazole carboxamide moiety were designed and synthesized in this study. The structures of the target compounds were elucidated using 1H NMR, 13C NMR, MS, and elemental a

Functionalized carbodiimide mediated synthesis of 2,3-disubstituted quinazolin-4(3 H)-ones via the tandem strategy of C-nucleophilic addition and intramolecular NH-substitution cyclization

A facile synthesis of quinazolin-4(3H)-ones possessing carbon substituents at positions 2 and 3 has been developed. Key to the synthesis is a tandem strategy involving introduction of a 2-substituent and construction of the quinazolinone framework via C-nucleophilic addition to the carbodiimide cumulenic carbon followed by intramolecular nucleophilic substitution by the newly formed NH moiety at the proximal ester group.

A facile synthesis of 2-amino-3H-quinazolin-4-ones with tandem aza- Wittig reaction

2-Amino-3H-quinazolin-4-ones 8 were prepared from tandem aza-Wittig reaction of iminophosphorane 5 with aromatic isocyanate and nucleaphilic reagent HY in mild condition.
