Biologically important quinazolinones have been synthesized from 2-aminobenzamides and DMSO. The key feature of the reaction is the utilization of DMSO as a methine source for intramolecular oxidative annulation. The CNS depressant drug methaqualone has also been synthesized by our methodology. The present method involves the synthesis of quinazolinones with a broad substrate scope and a good yield
valuable compounds including central-to-axial chirality transfer, dynamic kinetic resolution, and phase-transfercatalysis. Importantly, novel P,N-ligands with a π–π stacking can be derived from heterobiaryls by chirality exchange strategy or synthesized directly from complementary phase-transfercatalysis by using the inexpensive chiral quaternary ammonium salt.

analogues with potent activityagainstasexualparasites equivalent to clinically used antimalarials. Resistance selection and profiling against drug-resistant parasite strains revealed that this antimalarial chemotype targets PfATP4. Dihydroquinazolinone analogues were shown to disrupt parasite Na+ homeostasis and affect parasite pH, exhibited a fast-to-moderate rate of asexual kill, and blocked gametogenesis
