2,3-Dihydro-2-aryl-4(1H)-quinolinones, which can be considered as aza-analogs of flavanones, demonstrate a wide range of biological activities, for example, as anticancer and immunosuppressive agents. 1 They also serve as valuable precursors of other medicinally important compounds, 2 and 3 which are often not readily accessible by other means. 3 and 4 The formation of 2,3-dihydroquinolin-4(1H)-ones is generally accomplished by acid- or base-catalyzed ...
