Versatile Quinazolinone Synthesis: N‐Bromosaccharin‐Catalyzed Divergence in 2,3‐Dihydroquinazolin‐4(1H)‐one and Quinazolin‐4(3H)‐one Formation

ChemistrySelect, Год журнала: 2024, Номер 9(12)

Опубликована: Март 19, 2024

Abstract In this research, we present an innovative and eco‐friendly methodology for the synthesis of a diverse array 2,3‐dihydroquinazolin‐4(1H)‐ones, featuring use catalytic N‐Bromosaccharin (NBSac). This novel approach is not limited to just one product; it extends efficient quinazolin‐4(3H)‐ones by harnessing visible light alongside stoichiometric (NBSac) as multifunctional heterogeneous oxidant. By uniting cyclocondensation oxidation into one‐pot sequential process, direct access achieved. The developed protocol characterized its user‐friendliness, metal‐free operation, wide applicability across substrates, ability recycle catalyst, making appealing sustainable method quinazolinone synthesis.
